If the things your psychologist gives you to do are too difficult or overwhelming or just not working, tell him and try to get new suggestions or start with something smaller. Therapy is difficult and painful at times but it shouldn't be too much so. I recently quit going to therapy altogether because it became so overwhelming it seemed impossible (a really bad idea). I've now started medication and plan on trying again with a different therapist. The point is, allow yourself to move slowly to avoid getting overwhelmed at all the impossibilities. At my worst, no one could convince me it was worth keeping going. Somehow, though, I did. I'm still figuring out if it's still worth fighting but I think it is, some days more than others.
