I think you have to go in the direction of your dreams, that it is too soon to know much about what you may or may not want to do or become and how easy/hard you will find it to do.

I would tell your parents about your suspecting you have OCD and see if they will take you to a doctor to check out your symptoms/treatment possibilities. It is possible that treatment will help you a whole lot and make working toward your dreams/goals easier.
