Hmm, I understand a lot of what you're going through. A lot of it is what I've currently been dealing with so I can empathize.

This trip will surely help you get your mind off things, I find it's always helpful to go out and enjoy myself if life is getting to me.

Keep posting though, it helps to let it all out sometimes! If you have any friends or family around you, maybe not too close with them but even if people you talk to once in a while, why not call them up and see a movie or something? It's also good for a distraction, you don't have to talk, and when you're watching a movie it pulls you out of reality for two hours doesn't it?

It's good that you have a support group nearby and you can visit the doctors. I hope you feel better soon, I know it's hard, but I believe you can make it through
