Please stick with therapy and what you think is right. My mother sounds so much like yours. When I first started therapy she used to say the same things to me. "What do you get out of therapy when you do not even talk to me" "You just need to stop feeling depressed because it is all in your head."
Please do not let her get you down. I agree with Ozzie that mothers can have a problem with therapy because they fear they will be blamed for everything. It is kind of ironic that when mothers act this way they are portraying themselves as being the problem.
Stay strong,
