I know that there are several possible causes of mental illnesses. My "treatment plan" with my psychologist is primarily CBT. I've read that some mental illnesses are sometimes caused by chemical imbalances. If this is the case with mine, I don't think CBT will do very much. Since I'm going to a psychologist, I can't get medications. I was wondering (I'll ask my psychologist this during our next visit), what is the chance of this being a chemical imbalance and is there any actual way to tell, or should I just see which treatment works for me?
