I understand what you mean all too well. I was suicidal when I was younger. (16) TBH, I have no friends right now either, and I'm also poor at the moment, plus I have major problems with paranoia. I have a completely bizarre lifestyle as well. I'm lucky to have a great family, my sister is the polar opposite of me (completely social) ..though I was much more social as a teenager, my behavior changed a lot into my 20s. I would like to make some real friends, I just don't feel motivated to do so anymore, usually. The main difference between myself and others on this board is that I'm not suicidal, in fact I seem to enjoy being an outcast for some reason.. That doesn't mean I think it's healthy and good though, it's just how I am right now.
I don't know what to tell you about the job situation. I'm currently doing freelance writing - which is a ton of work and pays poorly.. but usually doesn't involve much social interaction. I do it because I enjoy art and literature, which means a lot more to me than money ever would, of course. Life isn't easy, there's not much I (or anyone else) can do except continue to face the challenges! I will admit that I think life can be a lot easier with friends and close relationships, and so I can only suggest that you find some people with similar interests, perhaps join a group, and replace bad friends/ memories with good ones, slowly but surely. This seems impossible when we can't trust others, but it will happen on its own when you're ready. That's what I believe.
I think you could use a break. Try taking some time to relax, such as taking a long bath or just having a delicious meal and resting for awhile, clear your mind or all thoughts or listen to some soothing music. Actually, I should do this myself. OR since it's spring time now, maybe find a nice park or lakeside area to spend in the sun. Maybe that will help a little, I can't guarantee, but it's worth a try. If bad thoughts return again, try to think of something you love or enjoy, to counter the negative tension.
