Hopefully you are asleep now (sometimes when I feel bad, I feel better in the morning) but if you aren't I do think it helps if you try to identify what you are thinking about when you are feeling depressed, then, like Só leigheas said--write it down--you can journal, post, or private message. It helped me to not run away from my thoughts. I'm not as obsessed with my attempt anymore but I spent alot of time trying to write/figure out what I was upset about at the moment I did it. So maybe try to figure out what is going on in your head when your depression is at its blackest?
