the norms are too self absorbed to care about you and there are other people who look and act just like you or even worse anyway, there will inevitably be some anxiety if you go and do certain things so you just do it step by step, my first time ordering subway was a very nerve wracking experience now after doing it enough times I don't care no mores and can talk more confidently. The first times I definitely sounded retarded but they never batted an eye
