I have never been diagnosed as having Obbsessive compulsive Disorder but I do have thoughts that go round and round my head and don't stop. It could be just that I said no to a friend and now I can't get myself off the topic or something as major as being anxios about not going to sleep because I just know Im going to have a nightmare or worry about an upcomming event even thought the event is a month away to the point where that is all I think about until I do something about it. When ever I tell therapists about this they call it obsessive thinking. So I know I have at the least the O part of OCD. and using the CBT type stuff of looking at all sides of the situation and so on that I have learned in my classes and in therapy do help.
