I think that is one of the toughest things about depression... not enjoying the things you used to. It makes me feel like I've lost a huge part of myself. It makes me really sad knowing that at one point I could live a life enjoying the things that made me happy. When I think of those things or see or hear something that I used to enjoy, it is a huge trigger because it becomes so obvious what depression has done to me. Now, it seems more like having to survive and get through each day as best as I can. And that pretty much sucks.
