#183 How to Stop Letting Your Past Define You
Have you ever caught yourself saying: “That’s just who I am.”
Maybe you’re the one who always apologises. The one who overthinks every message. The one who expects people to leave. The one who works twice as hard because somewhere deep down, being ordinary never feels like enough.
And because you’ve been that way for so long, it feels like personality - It feels like identity. But what if it isn’t?
What if some of the things you’ve spent years calling you are actually strategies your brain developed after something painful happened?
In this episode of Molly’s Playground, I explore how trauma and difficult experiences can quietly turn into beliefs about who we are. We’ll talk about why the brain clings to familiar stories, how old survival strategies keep showing up long after we need them, and why healing isn’t about pretending the past didn’t happen.
It’s about learning to separate: What happened to you from What you decided it meant about you.
Because your past may explain you - But it doesn’t have to define you.
How do you stop letting your past define you?
You begin by separating the event from the identity you created around it. Painful experiences can lead us to conclusions like “I’m not enough,” “people always leave,” or “I have to earn love.” Those thoughts can become familiar enough to feel like facts, but familiarity is not the same as truth. Healing begins when you notice the story, question it, and start collecting new evidence instead of automatically living from the old one.

Your Pain Is Not the Same Thing as Your Identity
One of the biggest lies we accidentally tell ourselves after something painful happens is: “This says something about who I am.”
Something happens.
Someone leaves.
Someone rejects us.
Someone criticises us.
Something frightening, confusing or painful happens at exactly the wrong moment.
… And our brain starts trying to make sense of it.
The event becomes a conclusion.
The conclusion becomes a belief.
The belief becomes a lens.
And eventually, that lens starts feeling like identity.
You don’t just think: “Someone left me.”
You start thinking: “People leave me.”
Then: “I’m not someone people choose.”
And eventually: “That’s just who I am.”
That shift matters.
Because it’s incredibly difficult to change something when you believe it’s your identity rather than something you learned.
We Don’t Always Remember the Event. We Remember the Meaning.
When my mum left when I was six, my six-year-old brain didn’t have the perspective to understand all the possible reasons an adult might leave. It made it personal.
That’s what children often do.
So somewhere along the way, the experience became: “If my own mum didn’t stay, maybe I’m not someone people choose.”
That wasn’t a fact. It was a conclusion. But the brain is very good at protecting conclusions it already believes.
So when someone became distant, I noticed. When someone cancelled plans, I noticed. When I felt rejected, I noticed - And every one of those experiences became another little piece of evidence.
See? People leave.
Meanwhile, I wasn’t collecting the opposite evidence with the same enthusiasm.
The people who stayed.
The people who cared.
The people who chose me again and again.
That’s what old beliefs do.
They don’t just influence what we think.
They influence what we notice.
Survival Strategies Can Start Feeling Like Personality
Maybe your version isn’t: “People leave.”
Maybe yours is:
“I have to be perfect.”
“I can’t rely on anyone.”
“I have to keep everyone happy.”
“I’m too sensitive.”
“I’m just an anxious person.”
“I’ve always been a people pleaser.”
And maybe those things have been with you for so long that you stopped asking where they came from. But sometimes what we call personality is simply a strategy that worked once.
Maybe perfectionism reduced criticism.
Maybe people pleasing reduced conflict.
Maybe staying emotionally distant reduced the risk of rejection.
Maybe being hyper-independent made life feel more predictable.
Those strategies can be incredibly intelligent. They may have helped you survive something difficult. The problem is that survival strategies are often designed for a version of your life that no longer exists. And your brain doesn’t automatically update the map.
Why Old Stories Feel So True
One of the reasons changing old beliefs is difficult is very simple: Familiarity feels believable.
If you’ve spent twenty years thinking:“I’m not good enough,” that thought has had twenty years of rehearsal. You’ve practised noticing it. Practised responding to it. Practised finding evidence for it.
So when you suddenly try: “Maybe I actually am enough,” your brain might respond: Absolutely not.
Not because the old thought is more accurate, because it’s more familiar. That distinction matters. A belief can feel true without being true.
Healing Isn’t Positive Thinking
I don’t think healing means replacing: “Nobody wants me.” with: “Everyone loves me and everything is amazing.”
That’s not what I’m interested in.
Healing isn’t replacing one distorted story with another. It’s allowing yourself to see a fuller picture.
Maybe the truth isn’t: “Nobody ever leaves.” Maybe it’s: “Some people have left. Some people have stayed. One person’s decision doesn’t determine my worth.”
That’s a very different kind of thinking. It doesn’t erase your pain. It simply stops giving one painful chapter permission to narrate the entire book.
What Story Are You Telling Yourself Right Now?
One of the simplest questions I use in my own life is: “What story am I telling myself right now?”
Someone replies six hours later. That’s the event. The story might be: “They’re losing interest.”
Your boss corrects your work. That’s the event. The story might be: “I’m terrible at my job.”
Someone cancels plans. That’s the event. The story might be: “People always leave.”
Once you can see the difference between the circumstance and the meaning you attached to it, you create space - And space creates choice.
You don’t have to immediately change the story. You don’t have to win an argument with your own brain. Start by noticing it.
Collect Different Evidence
For years, my brain was basically a detective with one job: Prove that people leave. And when that’s the case, you’ll find evidence everywhere.
So eventually I started deliberately asking a different question: “If I wanted to prove that people do want me in their lives, what evidence already exists?”
At first, it felt unnatural. Of course it did. My brain had years of practice with the other story. But slowly, I started noticing things I had previously filtered out.
Someone checking in.
Someone choosing to spend time with me.
Someone staying after conflict.
Someone calling.
Someone inviting me.
Someone loving me without requiring me to earn it.
I wasn’t creating fake evidence. I was finally allowing myself to see evidence I had ignored. That’s an important difference.
Your Old Thoughts Don’t Have to Disappear
I still have old thoughts sometimes. Maybe you’re too much. Maybe they’ll leave. Maybe you need to prove yourself.
Healing hasn’t meant those thoughts disappeared. It has meant I don’t automatically obey them. And I think that’s a much more useful measure of progress.
Not: “Did the thought show up?”
But: “Did the thought make the decision?”
That’s where your freedom starts returning.
Your Past Explains You. It Doesn’t Define You.
You are not the worst thing that happened to you. You are not the belief your pain created. And you are not every survival strategy your brain developed to protect you. Those things may explain you. They may explain why certain situations feel difficult.
Why rejection hits hard.
Why you overwork.
Why you apologise.
Why rest feels unsafe.
Why love sometimes feels difficult to receive.
But explanation is not identity. And history is not destiny. Your pain may have written the first chapter. It doesn’t get to write the rest.
Key Takeaways
Painful experiences can create beliefs about who we are, but those beliefs are not automatically facts.
Survival strategies can feel like personality when they’ve been repeated for long enough.
Familiarity often feels like truth simply because the brain has practised it for years.
Healing isn’t about denying your past. It’s about questioning the identity you built around it.
You don’t need to eliminate old thoughts before you can make new choices.
New evidence matters. Your brain may simply not have been trained to notice it yet.
Progress isn’t measured by never hearing the old story again. It’s measured by how often you choose not to obey it.
Your past explains your starting point. It does not get to decide your future.

FAQ
Can trauma change your identity?
Trauma and painful experiences can strongly influence the beliefs you develop about yourself. What happened may lead you to conclusions such as “I’m not safe,” “I’m hard to love,” or “people leave.” Those beliefs can eventually feel like identity, but they are still beliefs rather than objective definitions of who you are.
Why do old beliefs still feel true even when I know they aren’t?
Because familiar thoughts often feel more believable than new ones. If your brain has rehearsed a belief for years, it becomes automatic. Understanding that a thought may not be true is the beginning; repetition and new experiences help create a different pattern over time.
How do I stop letting childhood trauma define me?
Start by separating what happened from what you made it mean about yourself. Ask what story the experience taught you, where that story still appears today, and whether there is evidence that challenges it. The goal isn’t to erase the past—it’s to stop treating your childhood conclusions as permanent truths.
Is people pleasing a trauma response?
People pleasing can function as a survival strategy for some people, especially when keeping others happy once helped create safety, connection or predictability. That doesn’t mean every people pleaser has trauma, but it can be useful to ask what the behaviour has historically protected you from.
Does healing mean my old thoughts will disappear?
Not necessarily. Old thoughts may still appear. Healing can look like noticing those thoughts without automatically believing or obeying them.
How do I change a limiting belief about myself?
Begin by identifying the belief, separating facts from interpretation, and collecting evidence that challenges the old story. You don’t need to force a completely opposite belief immediately. Curiosity is often a more useful first step than positivity.
Further Reflection
Before you move on with your day, sit with these three questions:
1. What have I been calling my personality that might actually be an old survival strategy?
2. What story did a painful experience teach me about who I am—and do I still want to live from that story?
3. If I started collecting evidence for a different understanding of myself, what would I notice?
You don’t have to find the perfect answer. Just become curious enough to question the old one.
