I too don't know how to conduct myself socially, but I don't know why. I feel anxious most of the times around people, but even when I am not, I just fail to connect. In my case, I feel I keep failing. I think part of the reason is my age, because when I feel I am failing, I withdraw because I think others are judging me how someone in my age is so ... immature. So, I really don't learn how to be ... resilient. That's why I said it's too late for me. The humiliation is proportional to my age when I fail.
