hi u nice lady, i do think having a T would help even if you see one for a short time. but i'm glad you reached out to your friend. there is an excellent form of therapy, CBT, and that is the therapy i receive. i believe this situation tapped/triggered a false belief you have about yourself. in your case the false belief might be, "i'm not worthy because other people think i am defective," to put it directly regarding your having to get help and it being revealed at your workplace. i used to say to my T "i just want to be normal. i'm defective." both meaning feeling less than others. does this make sense? a T could help you toss out the false belief and replace it with a true belief. such as i am worthy because....
if you want to really get beyond this so it won't rear it's ugly head again it would help to see a T. otherwise later it will get triggered again and you will have the same upsetting reaction.
at any rate hugsto you. i hope you will feel better soon. i'm just making a suggestion based on my own circumstances where i found a solution. even now i can get triggered but my response to it is improved.
