First i usually get really depressed, and go into the self pitying "Why god, why?" stage. I then self abuse myself in some way, thinking stupidly that somehow physical pain/injury caused to myself will distract me from emotional pain, or at least give me something else to do. After that, I become angry at the world, and become kinda rebelious. While I'm angry, I'll look back at how dumb of me it was to cut myself/get drunk/do some other stuff, when i should've been hurting the people causing me pain, not myself. I then turn to my beloved drum set, and after an hour or two, I'll feel better. Then i continue on with my week, happily.
Music and anger is the answer to feeling better. No matter how bad a week is going, when i do something i love, it all gets better. If only for a little while.
