I find my OCD to be strange and my doctor hadn't heard of it before. I have 2 things that I do. number 1 is I count on my hands, but its not exactly counting, people can be talking in movies or to me and the words they are saying I get each letter from the word and put it on each finger back and forth on my hand. And I like it if the words end on the end of my hand otherwise I have to find one that does. Sometimes its worse than others, especially when i'm stressed. The second thing I do is I pick my skin in my ears. It builds up to like this white flaky skin and I just pick it out of the edges until its all gone to the next day. And I cant stop no matter how I try. Gets annoying!!!
