Should I let go? Serious help only!?

Okay, Im going to try to make this as short and interesting as possible.

I live in Wisconsin, and I met a girl 4 years ago in Colorado (family lives there too). And since then I have gone to meet her and my family every year. But this year, and last year, I did not.

We were friends at first. She was nice, and I just wanted to be friends. But lately, I have realized we have tons in common, she really understands me, and i really understand her. But there is a good chance I will not see her for another year.

I have grown connected to her, and she says she is dying to meet me again, and I am too. I'm getting butterflies when I think about her, and I feel depressed when I think about meeting her (because it could be awhile). I feel like im falling for her... but I don't know how. I have never been in love anyway (so i dont know what its like lol)

We stay connected via texting, e-mail, and calls. Basically every day now.

So heres my question... let go? or go for it? Could I make this work? Im 17 (no age flaming for God's sake) and still planning for college. I believe a lot can happen, but for real, can I make this relationship happen?

Should I try to meet her again? And if it works go to college down there? or is that stupid? Or am I just being a nieve idiot, and should move on?

All advice appreciated...

thank you :D
