I'm Crushin' Hard On A Student...

Okay, so I know this is going to sound super silly and maybe even a little bit weird. But here's the thing... I've been having these feelings for one of my students lately. You know those butterflies you get in your stomach? Well, let me tell you, they're flying around non-stop every time I see her smile or hear her laugh. It's not like I have any chance with her... she's young and I'm old enough to be her teacher. Plus, it feels wrong on so many levels. But still, my heart can't help but flutter whenever I think about her. Am I the only one who has ever felt this way? Is it just a phase that will pass... or is there something seriously off with me for feeling like this? What should I do?
