It's incredible to read your story. I'm sorry for what you went through.
It also re-affirms my belief about the solution:
But I decided to do no harm. I started thinking about it as a sort of superpower I have, one that must be used with great care and responsibility.
i.e. Accept it, and deal with it.
This is huge. Most sufferers find that impossible. Because....
you have to acknowledge and face the pain you've caused, which can result in unbearable guilt.
It can get better. Living a quiet life is better than a life full of extreme highs and lows. It feels emptier, because it isn't full of drama. But it's how most people live.
