I can relate SOOOO much. I am really sorry you're feeling so bad and that his comments hurt you. I feel really bad for you.... I've been there. My old therapist-- SHE would get all dramatic whenever I cut and pull out the "I'll call 911" card. UGH. When I was just doing what she told me to do--let her know if I wanted to cut. Etc.
Thankfully I have a new therapist who takes it all in stride, and that helps so much. But I used to be so ashamed, on top of what I was already feeling. Your psychiatrist PROBABLY meant well...and obviously has your safety in mind. So that is something you CAN trust about him. He wants you safe. But yah, it didn't come out very well did it? Can you try talking to him? Write him a note? Send him this post?
