I have a fairly severe case of OCD.
I've never been professional diagnoses, but I know I have it, but not in the usual way. I don't wash my hands 20 times, or touch an object 30 times before bed, or knock on wood.
But if i'm about to do something - like make a post - i'll get an OCD feeling. If you do this, you'll get cancer, and the like. So sometimes, in order to 'surpass', OCD, i'll edit a post. Make it seem 'odd' so OCD doesn't mind me posting.
