It took me years, maybe decades, to realize that I actually don't like socializing, as it is practiced on this planet. I decline invitations to family events, work parties, whatever and have been so relieved since then. The quality of my life has gone way up.
I can handle a group with maximum size of 3, or 4.
Although from your perspective I am sure it is hard to believe, but I feel more alone, lonely and abandoned in a large social group than I do when I am totally alone.
