Hi, it's often hard to get started with therapy learning to trust the psychologist. I like FrancesR's idea of writing stuff down and taking it in with you, it can help the psychologist to help you talk. Learning to show your feelings when you feel safe with her will give you skills to help make coping easier potentially.
I also agree that a medication review may be a good idea, you sometimes have to try a few to find one that suits, if it helps you feel a little better it will be easier to make the best of therapy. Hang on in there, recovery is possible and it does happen.
