That was a very, very interesting post, jaynedough! Thanks a lot!
I think I might have a little anhedonia "in-the-moment", realized this the other day. But it's not much and I guess could be a result of other aspects of my illness. I really like how this post describes the anticipatory anhedonia, it's very accurate IMHO. I have never been to a reunion, very rarely visit my friends, and I have severe motivation problems + issues with blunted affect. It makes a little more sense to me now. But I do manage to get past the blunted affect with many people when I'm not tired (I am usually tired). Some people it is easier with.
I guess when I do physical tasks, it brings me almost no joy at all. Like showering, chores, going to appointments or doing yard work... all such things. I'm not sure that's very abnormal though. But many social things do bring me joy. Like going to lectures if I have friends there. Or doing yard work with friends.

But of course if I'm with strangers, I'm just stressed out. I didn't realize this until just now, reading this post!
