I'm not sure how to start this so I think the most logical is to provide some background about myself. I'm 21 going to turn 22 in like less than a week Indian American male. To a lot of people, I'm sure I seem like I've got my life together. I got to a prestigious university, have a path for what I want to do professionally, lots of ambition, among other things.

The problem is that to get to this point I had to give up a lot of my social development and social intelligence and trying to get to a level that is on par with my peers is proving to be a big challenge. For example, I have a younger sibling who is more socially adjusted than I am. The problem is that my sibling thinks I'm weird and we had a big fight a few nights ago over something minor and point blank called me weird and told me that the things I do aren't normal despite my efforts to try to better myself. They then proceeded to tell me how shameful it was that at 22 I don't have the requisite social skills to be a functioning member of society. I know they don't mean to hurt me but nevertheless what they said cut DEEP and it's made me wonder if my efforts are going to be fruitful or not. Another thing is that for some reason, things I think are normal and what I would expect to be seen as normal aren't seen as normal. One example was yesterday, I wanted to sit in an open spot that just so happened to be next to my sibling and they just pushed me away to sit somewhere else. Another time that same day, I asked them what food they brought home and they just told me to take one and see for myself instead of just answering my question. These events and some more lead me to believe that this whole social adjustment thing is all in my head and that my sibling isn't socially adjusted either but I can't be sure. There's some important details I'm purposefully leaving out for the sake of online anonymity but if it needs to be given then I will provide it. There's also been events and stuff which my sibling has led to let me know that I have problems with a Victim Complex and generally just being clueless about other people and stuff. There's also things with boundaries which I've had a hard time understanding and it's been pretty detrimental to me and my relationships and also overexaggerations. The cluelessness is super bad and it's something I've been working on. The main question I want to ask then is, what does it mean to be socially adjusted? Is it like some kind of spectrum? Additionally, how does one fit into communities that are different from the one they're from, be it geographically, culturally, racially, etc.? And, is there anything I can be doing to improve my social skills and get to a point that is appropriate for my age?

I appreciate the help!
