Oh yes, from the time I can remember, I was anxious and uncomfortable around other children. Adults were not so scary, but now that I am one, I am about as anxious around adults as I have always been around people my own age and younger. It helps that I know now some of the reasons why, but it doesn't make the experience any more comfortable. One thing that has helped is to choose my environments very carefully, especially the workplace. I maximize social gatherings with people I have a lot in common with, not necessarily the most familiar, but any old friends or new with whom I feel I can be myself and relax. Even family have to be taken in various doses, depending on the relationship and the environment. I can't change my genetics, and with relatively optimal environmental conditions, I don't even want to.
