What is it that you want to be doing? Can you temp while looking for something else? Also agree with Pillbug about the volunteer work. It does help to get your mind off your problems temporarily, esp. if you're helping those who are worse off than you are. Also maybe look into interning somewhere you want to work.
Totally understand the self loathing, been there. I used to have horrible problems with depression when I was younger (been on antidepressants as well), it still bothers me a bit from time to time but not like it used to. What I realized eventually was that negative emotions tend to have their own weird but very real momentum, its like being caught in the undertow, and they can literally "pull you under". You have to break that momentum somehow, its kind of hard for me to put this into precise words. I don't want to come off as being all "pull yourself up by your bootstraps" or "just snap out of it", I hated it when anyone would tell me that, esp. relatives.
You know what does help though? Meditation, exercise, hell go for a long walk someplace you don't usually go. Its not a permanent cure or anything but it will help.
