After reading all this, and your replies, it seems you are looking for ways to feel bad about yourself. You are even fishing here, to get others to say things to you, that will help you feel bad about yourself. Going by the fact you are in a strange country, and doing well, and dealing with all the challenges involved, I would would say you got much to be proud of. I do not consider you to be "socially isolated". You are doing quite well.
