Well, I can understand why you would be scared and fairly so. However I am sure that this guy knows you quite well, I don't know how, maybe you don't know who he is, you may have no clue but he knows you well otherwise nobody would write this message like this. I am sure he is someone who either stays close to you or is in your college and sees you regularly or something.
Is this the first time you are receiving such message or have you received such messages before?
