I've let it pass as best as i can. I'll gain nothing from going over it again and again but more anxiety and depression, which is bad whem i didnt have T. You have to move on when you can. What's done is done I am afraid.
I've experienced pretty much the same as you @Forever hopeful These negative thoughts of guilt, and "why? why me??" was spinning around in my head for a long time. In the end, acceptance that I cannot change what's happened, is the only way forward imo. Its often a long process though, for most people, getting there.
With forgiveness and self love. I think guilt and shame add many layers of stress and compound our problem. Possibly increasing our awareness making it seem so much worse. Please give yourself a break.
