I don't have much advice, but I do believe in the power of music as a guiding and uplifting force (and it can take you the other direction too if you let it). I just saw Streetlight Manifesto in your sig, and this song has gotten me through some dark times- (guess I can't post links yet, but the just youtube "A Better Place, A Better Time" if you're not familiar with the song)
Hope you get it figured out and start feeling better! Continue to listen uplifting (and kickass) music along the way
