My bff is my crush and I fear it is hurting our friendship

Hey

I am in highschool right now and I'm in a tough spot. Me and my bestfriend, lets call her JJ, are really close. People often mistake us for dating and the truth is that I have liked her since the origin of our bond. Recently, the besfriend love I have had for her always has turned into this incessant infatuation. Well, I guess it is more than infatuation but love in a different perspective than she loves me. Idk why, but this feeling is extremely strong. She never has been a consistent texter, but now I have a feeling of loss when she doesn't reply and I find myself almost angry. We have both liked others in the past and dated. I haven't dated in over a year and she has been single for less than that, but her relationships aren't that often and do not last long. Some think she is crazy because when she likes someone it is a kinda crazy state, or obsession. Last school year, me, her, some of our friends, and the dude she liked was at a soccer game and when one of our friends, a girl, started speaking and joking with him, she got up and stormed off in a rage of jealousy. I wish she would feel the same about me. I now find myself feelings jealousy when she is goes out without me or is talking to other dudes, nothing too serious though. Depression has overcome me in the past few days when she stops replying, but yet tweets or posts on instagram. I often alienate myself from my close friends when I become depressed and i really think i need to talk to someone about this. Can almost 100% say that i am infatuated, but placing a label doesn't help anything. I'm not sure whether to distance myself from her or to confess my feelings, risking our friendship in both instances. I don't want to keep going on chasing an infatuation that doesn't have the same feelings for me. I would like to think that i'm one her, if not the #1, close guy friend, but that's it...a friend. Please help with any advice on what i should do.

PS im new to this site. I never thought i would be on a relationship forum for help, but i'm glad i came. Any tips on how to recieve the best results would be very much appreciated as well.
Here is a poll as well for those would dont want to type a response

Get it over with. Get out of limbo. Just don't have any expectations.

What about our friendship?

That friendship isin't worth $#%^ if it makes you feel this way. Tell her how you feel, and if she says no, move on.
