Is it obsession or is it a schoolgirl crush
Ok, first of all, I am a college freshman and have been in college for about two months. Well, I developed this crush on a guy (upperclassman) at a pre-college gathering a few weeks before I entered college. I figured nothing more would come of it, as I was sure I would never see him again (its a big college). Well, I was wrong. I see him all over campus and what's worse is that I can't get him out of my head for a single second of the day (even in my sleep he invades my dreams). I barely know him, since we never exchanged anything more than pleasantries (hello, how are you, etc.). I dream of the moments each day that we may run into each other and sometimes when I see him, but he doesn't see me, I'll just stare at him. And I stalk his facebook.
I feel like such a voyeur, always watching. And its crazy that someone could invade my thoughts so much when I haven't had many one on one conversations with him.
Am I normal? Or is my schoolgirl crush nothing but an obsession I should get help about?
