I know exactly how you feel. Haven't been on one date in 7 years after the breakup of a live in relationship that I thought was going to be the love of the rest of my "older life".
e ended up having "borderline personality disorder"
Then I experienced a series of 5 other traumas that I won't list here but believe me you would find it amazing.
I don't want to be around people, never see any of the few friends I did have for years. Never go out or anywhere I used to go and have a hard time feeling anything but sad or anxious.
I feel OK if I stay very quiet and alone but that is just making me worse. I get feeling hopeless too am also very discouraged by the state of the world.
I realize tho that the ONLY way to break out of some of this is to force myself to get out.
I think I am going to force myself to go to the city to a museums just for starts but first I have to get thru an appraisal on my land which a critical loan depends on. Then I will try to go. You can't imagine how worried I am about it.
Why don't you think of one thing you could do that you might be able to enjoy.
Share here what that might be and then commit to doing it and report back.

I hope you feel a bit better tomorrow, it is after all "another day"
