That roughly how the first part of your advice comes across. You are not the first and won't be the last. I bear you no ill will for saying it, but it's on the level of telling a depressed person to just stop feeling sad.
I don't know if I'm diagnosable as actually having Social Anxiety. Heck, I never even heard those words until some drug commercial came on TV, so I'm a bit suspicious of the label.
I do know that I see social experiences as different than most people. I've always been that way. Just a bit different in the head I guess. I like different things, think differently, and behave differently. It's part of who I am.
I'm very much the old-school nerd. The one that everybody rolls their eyes at when he starts speaking. I care about things they don't. I don't care about things they do. So it's work for me to communicate with others in a way that doesn't make them roll their eyes. Yes, it's a skill. I'm better at it than I used to be. I could probably be even better at it. But it sure won't be because I stopped caring. If I do that that I'd become an oblivious blowhard.
