I'm sorry you are struggling. I had remembered someone else here feeling very numb and she posted about it but I couldn't remember what it was called. I was amazed at all the old posts here that I have no memory of reading or responding to as I was looking through old posts, lol.

Anyway, this member talked about something she called Anhedonia. I don't know if it's what you are feeling or not but thought I'd bring it forward in case you were interested in reading it. Maybe it will help.

Take care and I hope you feel better soon.
