Sounds like you are at the hard part of living by yourself abroad. The newness has faded, and you are feeling very alone.
Well, this will pass. Everything does. Hang in there. Maybe look back at the reasons why you selected this country and make some new goals to give you a new purpose ?
Personally, getting outdoors is a great help to my mental state. Is there hikng, bicycling, something like that? Gets you out. Maybe join a hiking club or something like it.
There must be some kind of ex-pat community around. People tend to seek familiarity when they are living abroad. Where can you find some Americans?
Last, there are AA meetings in every country throughout the world. The fellowship can be a great source of community. Go find one.
That's all I have. Good luck.
