Hi cg92 and welcome. You've come to the right place because people here a really supportive and there is a lot of information for you so you can better understand what is happening to you.
If I were you I'd get medical attention as soon as possible. I'm no Dr. but many of your symptoms sound very familiar and I'm on medication for depression and anxiety. It is working very well for me but it took many trials before my doc got the mix correct.
About your financial situation. I'm happy to hear that there a community college where you live. There are several short term programs for trade type work that might help you get started. Trying to follow a 2 year course just might be too much for you right now. The school ought to have a career counselor who can suggest some avenues to follow. I went to a community college to get my LVN which took 1 year which supported me for a long time. Then I went back when I was 51 to get a 2 year RN. I wasn't able to stay with a 4 year college program. I think there are several short term courses for these types of professions.
You say that you spend a lot of time on the computer. What kinds of things do you like? I like casual games like mahjong and hidden object games.
I hope you feel better soon.
