I personally don't have OCD, but I do have 'OCD tendencies' (apparently) that are set off by anxiety and depression. I had a therapist tell me this a while ago, and I do notice it more and more as I get older. I have noticed many people who stutter also have OCD, or have pretty bad social anxiety. I was born with anxiety, but I am sure the social aspect is worse because of the stutter, and then the stutter makes the social anxiety worse, and the cycle continues.
