my insecure self

I was diagnosed many years ago with bipolar disorder. I have been unmedicated successfully for about 3yrs now. I finished nursing school and have a great job. I also just married the most wonderful man ever. I am now dealing secretly with untrusting thoughts for no reason. I escalate my thoughts and have to stop myself with prayer, but they seem to be getting worse. I don't want to be medicated again. I am struggling with obsessive/compulsive ways to catch him doing wrong and he's not. Why do I feel that I am losing control of my thoughts even though I've had them under control for so long? Is there anything I can do to keep myself mentally healthy from this horrible mental anquish I am dealing with?

You don't want to me medicated again, but Prozac in high dosages is usually recommended with OCD, obsessive/compulsive disorder.
