Hmm how do u find a gf in a foreign country?

Well it doesn't sound like you have been living there for a very long time. If I were you I would try to make some new friends and meet people who will introduce you to more people. Honestly, I would feel very lonely too if I were in your situation. What I would do though, is just try to meet people. Are there any sports or interests you have? If there are, join a group and talk to people. You could try some more local online dating. I would stay away from a prostitute, that will make you feel even more lonely than you currently do. If everything fails are you end up very sad, consider relocating to a place you would feel more comfortable in.
