Welcome to the forums! You've come to the right place :)
First of all, congratulations on finding a job this week! That is a HUGE accomplishment under any circumstances, but especially now.
Your situation sounds so hard and lonely, I don't think anyone could blame you for turning to food as a source of comfort being so far from your loved ones for so long. We all do it from time to time. I think your instinct to go to the doctor was a good one if only just to talk a bit about how tough you've been doing it lately. It's possible they will prescribe antidepressants, or might recommend that you talk to a counsellor, which is another fantastic option.
The good thing about the forums is no matter how far you are, there's a really vibrant community here at pretty much all hours!
What else are you interested in? How do you like to pass the time?
