I have OCD I have never went to a doctor for it, But I know I have it. I check and recheck the door , stove things like that befor I go to bed, some times getting back up to do it again. I use to be pretty bad a bout it but I find that it has gotton better. I also go with evens not just evens but some times in fives. dont know why that is for sure, but I do. some times I drive myself crazy with it all.
