OCD works in a lot of ways... they arent really any different "forms" as such, the condition just depends on which anxiety it picks on in a sufferer. It can move from one anxiety to the other, leaving you thinking "okay, so Im not worried about that anymore, but why am I worried about this now?" The true forms of OCD are Pure O and the regular kind, but then again, they share similar anxieties, the two variant forms just differ in the way an individual expresses/deals with the anxiety.
You're not stupid.
I have experienced this also at times. I used to remember happy times with people important to me, replay situations and how I felt at the time, so I would never lose those feelings. Of course, is just an OCD fear of losing someone important to you. The kind of obsessions people experience are likely endless. As people are endlessly unique, so are theyre obsessions... I wouldnt put anything anything past OCD.
