I have been diagnosed as having OCD twice. My symptoms have been perfectionism in my life situations (such-and-such didn't go well or I made a mistake, so it's ruined now - screw the whole thing), obsessive and intrusive thoughts that I have to do something else to cancel out and hoarding items without realizing thats what I've been doing (then getting rid of as much as I can until I nearly have nothing so I feel like I can breathe again, but which also gets difficult because sorting through things has to be categorized and sub-categorized and so on and it takes forever).
I am always worried about what could be in my food, water or on my hands that might make me sick and tend to only cook enough to eat in one sitting so I don't have to deal with leftovers that give me a weird feeling to eat because I know its "older". I also worry about what I am capable of or what could happen to me sometimes and its usually something bizarre that wouldn't even happen, like.. "Hey, what would happen if I suddenly jumped up on the table in this restaurant and started doing that Russian kicking dance and sent everything on the tabletop flying, then grabbed a steak off someone's plate and ran around slapping people with it before getting hauled out by security while trying to bite them?". I know that would never happen and I wouldn't want to find what would happen if I tried it, but I still get these kind of thoughts anyway. I also fear getting in trouble (with people, the law, etc) even though I don't have any problematic tendencies that would allow for this to happen.
