**HELP PLEASE!!! DON'T KNOW WHAT TO DO!!! NEED HELP ASAP!! SERIOUS MATTER! THANKS!!*?

So I am having a dilemma right now. Okay, so there is this really gorgeous guy at my school (university), I have seen him around campus a few times but have never talked to him and don't know anything about him, not even his name :( Anyways I think he is the most gorgeous guy I have ever seen in my life, ever. So whenever I see him, which is not very often, I cannot help but look at him, I can't control it, my subconscious is telling me to look at him. The thing is, I think he has noticed that I keep looking at him everytime I see him and it doesn't look like he likes it really because now when I look at him, he like looks away, kinda looks mad...I totally messed up, now he must think I am a creep or something..he must have thought I was staring at him for some other reason...I don't know what to do, I feel bad and am sad :( What do I do????
