I've been diagnosed with OCD and bipolar 2. OCD runs in my family and I have things I do that are consistent with OCD. I obsess over subjects/things/activities for days/weeks/months, I really like even numbers and try to "fix" odd numbers so that they can seem even. I eat small candies in pairs and when I chew I have to feel like the left and right have been used evenly (though I don't count). I also do this thing with my fingers on my left hand when stressed and occasional when bored. It's something that starts off subconscious too. I could go on.

So, I have both though the OCD isn't severe or anything.
