To be honest, I'm lovesick and I've never experienced anything like it before. I'd love to be able to forget this person, but I can't seem to.

Keep yourself distracted with something else. Even if you keep thinking of this guy, that won't last forever, your mind will get bored of it and will find something else to do anyway. So it's better to just make new connections now. No use in thinking about something you have already thought about for the 500th time ya know ?
