Have you ever been sort of obsessed with someone...?

You are not a freak, you are just blinded by someone else's beauty and have forgotten all about your own. Originality, makes a strong independent person, and is far more attractive than a clone of someone else. Look at yourself, what do you have that she does not. Those things make you original and should be worth appreciating. Do not fall into the habit of comparing yourself to others because you will develop a self hate that will lead to self destruction.
