Why do I still crave my ex even though they treated me terribly?

Because your brain doesn’t distinguish between a “good” reward and a “harmful” reward when it’s addicted. If the relationship created intense highs - even if mixed with terrible lows - your dopamine system encoded the person as the source of those highs. Withdrawal is withdrawal, whether the drug was cocaine or a narcissist. The craving itself is not evidence of love; it’s evidence of conditioning. Start noticing the craving as a physical sensation and stop telling yourself the story that it means you’re meant to be together.

How long does it take to rewire the brain’s addiction to a person?

On a neurological level, new neural pathways start forming in as little as a few weeks of consistent practice, but the deep restructuring of self-worth takes months - often six to eighteen. The acute withdrawal typically peaks around three weeks and then gradually fades. But be wary of anyone who gives you a fixed timeline. The body heals in its own rhythm. What you can trust is this: every time you resist the compulsion and choose a self-soothing practice instead, you’re building a new circuitry. The investment compounds.

What’s the difference between self-worth and self-esteem?

Self-esteem is often performance-based: I feel good about myself because I achieved something, look good, or am loved. Self-worth is the non-negotiable knowing that you have value simply because you exist. It’s the bedrock that remains when the job is gone, the lover leaves, and the world forgets your name. That’s what this work aims to restore - not a pumped-up ego, but a quiet, unshakeable “I am.”

Can I really rewire my brain without years of expensive therapy?

Yes and no. The daily practices - somatic resourcing, journaling, breath work, self-touch - can dramatically shift your neurochemistry without a therapist. But sometimes the wound is so deep, so entangled with early attachment injuries, that you need a skilled guide to help you untangle it. I’m not anti-therapy; I’m anti-bypassing. If you can afford it, find a trauma-informed practitioner who understands the body. But even if you can’t, commit to the daily practices. The brain is wonderfully plastic and responds to repeated, embodied care. That said, be patient and kind with yourself. This is deep work. You are not broken. You’re in withdrawal from a very potent drug that also, once upon a time, held your hand and made you laugh. That withdrawal is real. But so is the power of your own attention. Every time you turn that attention inward, you light up a new neural constellation. You become the love you’ve been chasing. Not as a cheesy slogan - but as a biochemical fact. And from that place, you’ll love again, with a wholeness that doesn’t need the other to feel whole. That’s the only kind of love worth having. You are loved. Not because you performed well enough. Not because you finally got it right. You are loved because love is what you’re made of.
