this is so true and has been one of my worst symptoms...its gotten better but flares in a wave. Minute details of things I haven't thought of in years, or exacerbation of something you can swear you made peace with years ago now becomes traumatic all over again. Or past regrets nag in your head.
I am more at peace than in acute - but like [...] says - its torture. Literally started thinking I had delayed ptsd.
This will lessen:) Talk logically and kindly to yourself during these times. I found it to help a bit.
