Hello Nomorecloudsneedlig: I see this is your first post here on PC. So... welcome to PsychCentral.

I'm sorry I can't tell you anything about what's going on with you. From what you wrote, this all just sounds like OCD to me. I have the impression, after reading your post, you think there may be more to what you're experiencing than OCD. But I don't know if there is. I'm not a mental health professional though. So that's just my personal non-professional opinion. Perhaps other members, here on PC, will have some suggestions they can offer.

Here's a link to an article by our host Dr. John Grohol, Psy.D. that goes into some detail with regard to OCD & also provides links to some additional articles, from PsychCentral's archives, on the subject as well:

Obsessive-Compulsive Disorder (OCD)

I hope you find PC to be of benefit.
