Sorry you're feeling down. I think it helps to know what's wrong because then I don't feel so crazy. It's like, if I'm dancing like a ballerina around the house and don't know why, it can be troubling, even to those around me. However, if I'm dancing like a ballerina around the house and know I'm bipolar, I realize that I'm in a manic phase. Then I can talk to my pdoc about increasing my mood stabilizer.
