Explore your sadness and use it for all it has to offer. People can relate to basic universal emotions, and you have a true gift of expressing yourself in words & music. As long as the song says what you're feeling, it has an audience.

Personally, some of my very very favorite songs are upbeat musically and depressing lyrically. The contrast makes for some fine tunes... Enjoy the Silence is basically about wishing you hadn't been told that things were over... it was better not knowing ("words like violence break the silence and come crashing in into my little world". Better the Devil You Know is about settling for less than you want and deserve, as long as the other person will come back to you ("I'll forgive and forget if you say you'll never go"). "Do Flies Walk Backward?" is about.. well... moonwalking flies. :)
