@bellydancer2008,
Well, I'm no doctor, but it sounds to me like you might be a bit depressed, which I imagine would happen if you were far from home and felt that medical professionals did not care about you.
I am not suggesting medication. However, you might want to see about a therapist, simply to have someone to speak with who can be objective. It should help to let out some of these feelings. Medication should not be dismissed outright as a possibility -- it does help a lot of people. But I would suggest trying talking first. It may be enough.
Another thing I'd suggest is getting some good exercise. It may be hot where you are but I am assuming you can be inside air conditioning. Are there gyms you could join? If not, what about home fitness equipment? It need not be anything large. I have weights, a stability ball, resistance bands and a mat. Total cost: less than $200. Exercise will (a) give you something to do, (b) help release some happy hormones and (c) give you a sense of personal accomplishment that I suspect might be missing a bit from your life.
