<human>: Could you distill the essence of the text into 1-3 sentences?

I've always been enthralled for most of highschool, I guess. She probably knows it, too. We hangout a decent amount. Recently, though, it's become unbearable for me. I feel like I'm running out of time to do anything since college is rapidly approaching. I always try to forget her in a romantic light, but I really like her. I'm pretty sure I haven't built up her image in my head, I know her well. I've also been feeling really sad lately (like a month or two), which I'm sure is brought on by this. I wouldn't quite call it depression, since the clinical term doesn't seem to apply to me, but I dunno, maybe. I just don't know what to do. I'm really tired of being sad, but at the same time Im afraid to do anything.
<bot>: I fell for my best friend, and I don't know what to do. It's bumming me out big time.
