Yes, I know the feeling well. I don't know just when I first felt that way, but I was very young, and I have felt that way much of the time ever since. I definitely don't feel connected to other people. I am not a misanthrope, but I am not bonded to my own species. It feels unnatural, but I have no way to change it. I also find it difficult to get along with people, because they don't see why I can't be normal, if I only "try" hard enough, and then they get upset because there is nothing for me to latch onto, that I can manipulate into making me fit their norm. I don't have any idea of how to fit their normal, so there is nothing for me to "try". I then get upset with them being upset with me. Fortunately, my life situation improved enough several years ago for me to now live alone. I am much less stressed now, and life is much more peaceful. No offence meant to my family, but I never want to live with others again!
I think you might want to try living alone, if you can manage it, or find another Aspy to live with.
