How do you get over someone you are crazy about?

Okay well there "was" this girl that I was like completely in-love with. She's a senior and today was theist day for seniors. I'm only a freshman by the way. And I'm a girl as well. But yeah I thought I would be able to tell her how I feel about her but it didn't happen. I'll most likely never see her again considering she's going to college; in Oregon. I'm in California btw. I have her on Facebook. I don't know whether I should tell her how I feel or just move on. Which is extremely hard if you ask me.

well , for me . it's better if you tell her your feelings . cuz she's leaving to oregon . you should tell her how you feel cuz you might never see her anymore . you guys would only chat and stuff on facebook . but it's better if you tell her your feelings . be true to her . cuz if she leaves to oregon and you don't tell her , you might regret telling her . so yeah . hopefully , she'll understand your feelings . :) good luck . :)
