I have to eat my food on my plate a certain way. For instance, I can't eat my steak until I've finished my potato. I can't eat my potato before I finish my vegetables. I get anxiety if I am asked to try someone else's food, due to the fact that it is out of order. I also get anxious if I am asked to mix items on my plate. It is to the point where even if I really want to try my steak I can't skip ahead. I have to choose ahead of time what I want to have left over or else I don't know where on my plate to start eating. Is this related to a personality disorder?

Every time i look in the mirror i have trouble seeing past my own flaws how do i find the good things about myself
