Well, I've had CPTSD since early childhood. Never liked crowds much. Became homeless for 20+ years and I decided to do street ministry to force myself to interact with people no matter how tough it was for me mentally. This was something I did constantly for years and while it's helped me in many ways I still have little desire to be around people and I still kinda find life to be pointless.
But a benefit from all this. I found my true identity and today, I'm at peace with myself even though this strange movie keeps replaying over and over again. It's still uncomfortable for me but I have a much better grip on it than I used to. So I don't have episodes that last too long even though they're quite intense still.
