It sounds like you need to look for some people to spend time with. They don't have to become your best friends, but since you know that being around people is helpful to you (and that's very normal and natural to need that), I would look for some.
You may have ideas about how to do that. Your school might have suggestions. You might look for somewhere to take dance classes, if that's something you would like to do.
I don't know how far away from your country you are. Very often there will be clubs for "ex-pats" (say, Swedish people in France) who get together regularly. It's sort of a networking thing.
I had an acquaintance here in the US who was here from Turkey for a year for educational reasons and she said that meeting a group of ex-pat Turkish people helped her so much.
These Psych Central forums can be a sort of "relief valve" to express feelings and to see that other people are dealing with similar problems. I hope that you'll continue to post here if you find it helpful.
Sometimes it can take a little while for these forums to start to feel familiar.
Anyway, my best defense against getting to that point is to work at keeping my daily life stable. Regular sleeping hours, healthy food, no skipping meals, and going for walks help me to feel more psychologically stable.
I'm glad that you have found these Psych Central forums.
