I think I have pure O?

Pure O is basically ocd.. but it is just your mind fking you over and over again replaying the same thought in your head torturing you with anxiety. I'm 13 and I don't know if I have this but I think I might.. Heres an example... Ill be thinking of when I was talking to someone.. and then Ill think of what I said to them, and then I wonder what they thought when I said this to them, and I play out every thought they might have had in my head until I imagine it the right way.. If I try to just forget about it, it sits there in the back of my mind taunting me not letting me enjoy anything im doing and theres been times I have took like 2-3 hours of my life just sitting there and replaying a single, stupid, pointless event in my mind. Should I go to a phyciatrist or something about this?
