Hi there!

I too have been diagnosed with "Pure O" and Bipolar. For me, my obsessional thoughts are homicidal, and suicidal. Of course, I would never act on these thoughts but they can be very scary!

To overcome the Pure O, I was in therapy for quite a while, and the therapy was called ERP - Exposure Response Prevention. Basically, I forced myself to think of the horrible intrusive thoughts until they didn't scare me anymore. I haven't had trouble with intrusive thoughts for over a year, as a result. It's a very difficult illness to have, but you can overcome it with a lot of hard work.
