Thanks for posting your stories. I've never been diagnosed with OCD, but looked at this forum today wondering if possibly I have some variant of it. Like you, I have intrusive thoughts of questions and intrusive visual thoughts. (I also have intrusive thoughts of people being intrusive in other ways), so now am wondering if it is indeed some form of OCD. However, I have taken fish oil and B12 for other reasons, and it hasn't helped with the intrusive thoughts.
