Your experience of yourself (or your selves) sounds a lot like how mine used to be. I'm pretty sure I had OCPD. If you decide to look into therapy, I had a lot of therapists over the years who didn't have a clue about personality disorders. The therapist I'm seeing now is a specialist in dissociative disorders, which is another way of looking at the experience of having two (or more) selves. The goal of treatment for dissociation has been to have the parts learn to cooperate and accept each other and eventually they can come together in one whole, more flexible, personality.
