Heya, not sure if this is OCD related but it sounds as though it might be.
I have this thing where if I'm doing something such as photocopying pages, I seem to give myself some kind of ultimatum... For example:
I run out of pages of this particular document, and I need to photocopy it a few times so I have more copies. I go to the photocopier, and choose the number of photocopies I need. I choose 3. Then for some weird reason, something in my brain thinks "If I don't photocopy one more to make 4, something bad will happen."
...what the heck!? I do things over and over sometimes because my brain tells me something I fear (dying, vomiting, loved ones dying, etc) will happen if I don't do this specific thing in a specific number or way.
It's really bizarre.
Is this OCD-Related? It seems to have a lot to do with even numbers as well. Such as wanting that 3 to be a 4, and not having the TV/Stereo volume on an odd number.
