I know how hard it is to go beyond an obsessional thought. People say - just think about something else--but that can be so hard. When I get out of control I do anything to distract my mind like reading or watching TV or playing simple games on my computer.
Reading peoples' post on this forum seems to let some of the pressure off. I think knowing you aren't the only one is very reassuring.
I agree that you should return to your Dr. It can take a long time to get the meds right.
Keep posting. I want to know how you get on.
