Is it normal that i can't stop thinking about a guy i don't know?
Background: I'm a heterosexual girl who can easily count all the guys I've ever been sexually attracted to on one hand - so, when I do like someone, I obsess a lot. I'm in college and there's just one guy in one of my classes whom I'm insanely attracted to. I don't know him (besides his name), and I've never talked to him, but I think about him constantly. It's making me act really weirdly, I'm messing up my classwork, I'm sleeping drastically less than I normally do, and I'm constantly a little upset because I can't figure out how to stop thinking about him.
