Thank you for your replies. I still intend to take this up with my pdoc. So far I've been able to manage my obsessiveness, it seems to fade with time and seems to coincide with mood swings.

Open Eyes - thank you for your response, the whole thing was triggered by fear and discomfort, and me wanting to know who exactly it was I was dealing with at the time. In some ways I guess it is a form of hypervigilance.
