You might enjoy reading Thomas Szasz, The myth of mental illness-- probably one of the best books from the 1970s (I think that's when it was written; I read it in grad school in the 1980's) about the social construction of mental illness. There is much theory in psychiatry and psychology from the perspective that we label people as "mentally ill" when they don't conform to social expectations. And that therapy can be more about teaching people to fit into "polite society" rather than helping them per se.

So I guess I get where you are coming from. It's great that you recovered from anorexia, but I'm sorry you are still feeling rejected because of your way of being in the world. I hope that you stick with therapy if it helps you, but it is always your choice not to seek treatment.
