Self-Preservation or Self-Sabotage?

I was talking with a friend recently and we found ourselves reflecting on trauma, and how deeply our past experiences shape our sense of self and our behaviour. It was one of those conversations that stays with you long after it ends. And somewhere in the middle of it, a question surfaced that I have not been able to let go of: how do you know where self-preservation ends and self-sabotage begins?

What You Went Through Leaves Its Mark

If you have ever lived through Adverse Childhood Experiences or been in a toxic relationship, what you went through leaves its mark, ingrained deeply in your mind and nervous system. This is not metaphor. It is biology.

You develop coping mechanisms to keep yourself safe, and those patterns become your unconscious responses. Over time, they become a part of your personality. Simply who you are.

And then you get stuck.

The Window of Tolerance

Psychologist Dan Siegel coined the term “window of tolerance” to describe the zone in which we can function and process emotions effectively. When we are within it, we can think clearly, feel our feelings without being overwhelmed, and respond rather than react. But trauma narrows that window considerably. For someone who has experienced early adversity or relational harm, the nervous system becomes highly sensitised. It learns to scan constantly for danger, even in safe situations. This is why, for many people, trusting someone does not feel like a choice or a risk. It feels life-threatening at a biological level.

This is the heart of why the line between self-preservation and self-sabotage becomes so blurry. Your nervous system cannot always distinguish between a past threat and a present one. What looks like pushing people away might actually be the body doing exactly what it learned to do to survive. This is an adaptation that once kept you safe.

The Privilege of Feeling Safe

I think it is such a privilege to have a secure attachment style. Not everyone starts there, and not everyone has the resources to find their way there. Mental health remains deeply undervalued, even in developed countries, and seeking therapy still carries real stigma.

Which is partly why so many people are turning to AI instead. It feels safe. Non-judgmental. Available whenever you need it. You control when it ends, and it cannot hurt you the way people can.

And yes, it can genuinely help.

But deep-rooted trauma and attachment wounds can only truly be worked through within real relationships. That is both the challenge and the necessity. Because the nervous system does not heal in isolation. It heals in connection.

Trust, or Not to Trust

So the question stays with me: how do you know where self-preservation ends and self-sabotage begins? Hindsight makes us all look wise. But can we really heal within a society built the way ours is?

Trust, or not to trust. Russian roulette with your heart.

Therapy is not about fixing what is broken in you. It is about finally feeling safe enough to become who you always were. And if you are not ready for that yet, that is okay too. Start where you are. Awareness is always the first step.
