a guy at my school is obsessed with me-

I go to high school and heres a guy in my math and english class who is obsessed with me.  i saw a notebook in my locker from his saying "hot brunette big tits lipstick school girl sexy b*tch" and i am scared of him bc he is following me everywhere. He tried to go in the bathroom with me. I kinda giggled at the note bc it was a remix of that one song lol.
