Am I a stalker......?

Over the past few years I have obsessed over 3 different guys who were much older than me. 2 of them were my teachers. The weird thing is that I've only ever had 1 or 2 mundane conversations with them at most, nothing interesting, but there's usually something about their personality that gets me "hooked". As soon as it starts I feel like I go into full-on stalker mode, I search the internet for every scrap of information about them (for one of my teachers I found his son's facebook and house address), I start admiring them from afar, I check to see if they're ever looking at me, and when they're around they're all I ever think about. I know this isn't normal and I would die before telling anyone I know in real life about this "problem",what can I do? I feel like such a disgusting creepy stalker.. Boys my age don't interest me
