Excessive

I have my down times and my not so down times, and recently, very recently, I seem to be on the up, and it's strange, because it's not like I gradually go from one to the other - no - it's quite the opposite, I snap into one, into the other, up and down without warning or predictibility. I thought the world was ending late last week, I felt like all hope was lost and I was so stuck in my own head, I was insane and obsessive and tortured. Saturday I had a hangover and it was a terrible day full of suffering, but something in that, something that I don't know seemed to have snapped me out of it, it's not like I gradually changed, I was a horrible mess one night, and the next night I was relaxed and enjoying some games and tv.
