How did you feel right after dropping the 'friends'? Not 10 minutes later or after you thought about it but the moment you decided you were done? If you felt relief or good it was absolutely the correct thing to do. I had a therapist who told me my mom couldn't have been that mentally ill while I was young because the house was clean. I understand his reasoning but 5 years ago she was diagnosed schizophrenic and is definitely mentally ill, she also still has a clean house. I'd actually switch therapists if I were you but that's your call.
