I know how you feel. It's not fun, and unless you have an area where you can hibernate it's not likely to looked positively upon in a work environment or around others. I was in such a bad state that everyone I came across (for the months after I was in depression following my episode) could feel my negative energy and I gave off a bad image. It's hard to be happy for others and joyful, I'm still not. Still have a lot of angers and few pleasures, but life has been getting easier for me as time goes on.

Understand you are loved and your personality is beautiful. If you are truly a person that can not stand to be this way then you know in your heart you won't always be. It's a mental state that you must overcome. Keep positive and work hard at thinking about good things. Music, humor, and fantasy land have been pulling me out the hole. You'll get there just know that and until then stay here. People have been very kind to me during difficulties, they will do the same for you.
