OK. Because if you had an antisocial personality disorder, then you would've needed a professional help.

As I said, I'm extremely not social, and it requires me a huge effort to socialize. The irony is that, even though I prefer to be alone most of the time, sometimes I feel so lonely. Of source, because I spend most of the time alone, my social skills are rusty to get along with people. So, I have this period of time where I feel so frustrated and lonely, but it eventually passes. I am getting used to this cycle.

I live alone, and no one pressures me to socialize. But when I go to my home country and be around family, socialization is a must, and I don't do well in it most of the time, and end up being judged as arrogant because I choose not to socialize.

Even though I'm not sociable, I will throw this: I don't have an advice for you except that if you are forced to do the social things, the result, most of the time, isn't a good one. You need to change your mind for your socialization to be genuine. It's better to not say a word than saying something not genuine.
