I googled the word and it was what I thought or had an inkling it would be. Not getting pleasure out of pleasurable things and I think yours is due to depression. You sound just like me before I go into one of my big depressions (I am a strange bipolar. I am stable for years, but when I get depressed, I get sucidial. I have been manic once and I was psychotic). I would talk to both to my pdoc and my T. You may not get any worse. But then again, you may go sucidial. I feel for you. I know how it is. And you got people around you who love you and probably have no idea what's going on. I can say hugs and all that, but better yet, get some help. Quick.
