You do describe traits which are obsessive in nature.
But to be diagnosed as having the disorder/label called OCD
there are certain criteria. so, you will need a psychiatrist
But even before that, think of this.......everyone has lot of things that we psychiatrists may call "traits" i.e traces of some symptoms..... believe me, almost everyone does.
But the main criteria for seeking help is if it is distressing/hurting you, if it is disturbing you a lot or to such an extent that your family/social/personal/work/student/other occupational life is affected or you are at a risk to self or others.
If these are present then do consult a psychiatrist
. Most of the time, at your age, you can be helped by talking therapies preferably (CBT etc) rather than medicines but medicines will also help (under a doctor's guidance please.)
