Help. I love my best friend and cant get over her.. :(?

So about a year back i met her in one of my classes, and thought she was pretty hot so i started talking to her
Over the summer that year we got closer and closer, i didn't really like her yet but we talked alto. She would help me with some girl troubles i was having and i would help her with her boyfriend troubles. Then came the time where she broke up with her boyfriend. I was overwhelmed with joy. I asked her about it and if she was alright, and her being cool, and confident she was pretty good at faking a smile. She was still in love with him and he still had feelings for her, so i didn't really want to make a move or anything, so i played it casual and kept in touch now and again, so that i didn't get to friendly.

About a week before school started again she started testing me, and we talked about relationships, and just random stuff that we thought about. When school started it had turned out that she had been in ALL my classes! What luck! We were both pretty happy about it and we ended up sitting next to each other in all of them.
A little while passed and i started liking her
We decided to go drinking with a few friends, originally it was my idea. I bought her alcohol for her, and the night seemed good, she kissed me and it turned to making out. It turned terrible once we drank too much.. I dint remember all of the night, but from what people have said, is that she started crying for her ex boyfriend, and i was calming her down. She would hug me and tell me not to go.
so i stayed with her, until her friends told her that they had to get her into the taxi and she wouldn't leave without me so i left.

This was the first time i thought she liked me.
After that night things got really weird and people at school bugged us about the night, after lunch we both decided that we needed to leave school for a bit to let people cool off. We skipped our last two classes and just talked. I didn't tell her i liked her, and reflecting back now it probably would have been a good time to say it.

Things eventually got better, and a month later i went to a party. I got drunk their and ended up telling her i liked her. She was drunk too but the morning after remembered. She was still into her ex and they started having a "thing" what luck..

Since she was in all my classes it is hard to ignore her, so we went on as normal. And tried to forget it for the time being.

About 3 months passed and i thought i was over her, until one night at a party i saw her making out with another guy and it hit me pretty hard. I was mad and waited untill later to talk to her about it. When i went to talk to her she was a bit drunk, but not too bad. she explained it to me saying that he was an older friend of hers who also liked her, but she didnt want to be more than friends with him, but he kissed her anyways. We hung for the rest of the night and danced a bit and had a good time. I was definatly into her again.

The following weekend to this i got drunk with some friends and ended up having an emotional breakdown. Me and about 4 other friends were just talking about life and me and another friend ended up in tears. His was about his family, and i couldnt explain mine untill i realised it was for her.
I walked around that night punching walls and buildings and my knuckles nearly broke. Later when i got home i went on facebook and started flailing at the girl. . She told me to text her in the morning, and i ended up saying i still liked her while i was drunk.

The next morning she texted me, but i ignored her for a few more days. We were in our second semester now and had no classes together so it was easy. Eventually i talked to her and we talked about us, how i loved her and that one day we should go out. She seemed cool with the idea, she actually apoligized for sometimes leading me on.

another 2 weeks past and she came over. We layed on my bed for like 3 hours just talking. We were close to each other, inches away. She showed me a naked picture of herself. and we pretty much felt each other up, with clothes on.

Valentines day came and i bought her a rose. We talked more about us and she told me it would be 'awkward if we went out, and she couldn't picture it.' i tried convincing her it wouldnt be, but no luck.
The following week i felt depressed, and everytime we talked it got worse. I told her its getting to harder to be her friend because i loved her too much and i was scared what i might do if i saw her kissing another guy, or worse dating.

Today we hung out, and talked more about us and nothing went well with it. She talked about how it would never happen. so today i also told her i couldnt be her friend because its too hard, and i need to get over her.. (i regret it) And now i cant lay down to sleep without nearly crying form picturing her kissing the guy she likes. its stuck in my head. And im going into a depression. What should i do? its getting pretty bad. i dont know if i can even go to school.
I cant imagine life without this girl. Shes simply amazing. Ive dated other girls, and had other crushes. But none compare to how i feel for her. I love her. Im my happiest when im with her, and i could talk with her for hours and never get bored. She completes me. And she doesnt see it.. :/

Were 16 by the way. And the guy she currently likes is 19. I hate when girls like older guys because it seems all girls go for older guys nowadays and i dont want to go for younger girls because they are all so immature.

[WHAT TO DO]:>> Block her PHYSICALLY from every goddamn book there is about the face to the leg! Cut her phone. DO NEVER EVER respond to her emails, SMS. NO MATTER WHAT!

SHOUT "NEXXXT!"; "NEXT", "NEXT!".."NEXT!", many times, till someone pleases you & is here to STAY! YOU CALL the SHOTS here! Duh!

GET SOME SELF-RESPECT DUDE! I'LL GIVE YOU SOME RIGHT AWAY- You're the MAN! You're the coolest thing that chick's seen & her BLINDNESS, DUMB-HEAD or EVOLUTION AIN'T your concern/problem! KICK HER (not physically). KICK HER WHERE SHE CAN'T EVEN SHOW. LOAD it with {{STYLE}} dude. LAUGH at her!

[GETTIN a GRIP on the "MISMATCH"]:>> "WHAT breakup?!"
<The T-SHIRT ANALOGY>: At a mall you see a REALLY artistic, exotic, umber-cool T-Shirt(girl). You think THIS IS 'THE ONE'! You almost buy (marry) it to live happily Eva after, but Oops! turns out it's 3(THREE) whole sizes smaller than yours. WHADYA DO?! Put it back to where you picked it from & shout "NEXT!". That's what!

<The KEYS ANALOGY>: So You're tr yin keys(girls) from a bunch to open this door. You pick a key, HOPE it'll "work", but it DOESN'T! OMG! WHADYADO NOW?! Drop It And Pick The NEXT! That's what! You waste NO time to sit & brood over "Why didn't the key OPEN it for me?" YOU'RE the DOOR! not some KEY! You hold back NUMEROUS GIFTS inside you. This person is ONE of the keys. If this key can't open it, 2BAD, it'll NEVER see your GIFTS! LAUGH NOW! The KEY "MOVES ON"! The door STAYS PUT! YOU CALL THE SHOTS!
Ts! Keys! MOVE ON! Somebody shout "NEXT!"

[CONSIDER THESE QUESTIONS]:>> Why would you treat someone on priority when you're NOT their priority?
Why would you live with someone who DOESN'T like your company? Why in the HE.CK would you enjoy theirs?
If she doesn't enjoy you, WHY WOULD YOU enjoy her NOT enjoying you, or ENJOY HER AT ALL?!
If she's OK with it, why EVER would you NOT be OK?! If she DOESN?T want it, why EVER would YOU?
If SHE DOESN'T mind, WHY WOULD YOU?! Why would you need someone that DOESN'T need you? WHA:O? whY.EVER?!
If SHE DOESN'T NEED you & WANT you as much, why EVER would you? Why would you care if SHE CAN'T/WON'T care?
Why would you be with someone who's willing to LET YOU DOWN, LET YOU FAIL?! :O WHY IN THE ACTUAL HE.CK WOULD YOU DO THAT?!
It's like wanting to live desperately with someone who you know will murder you! WHY WOULD YOU DO THAT? KICK HER! She more than deserves it.
BASICALLY, why would you be with someone that FAILS YOU & is WILLING to LET YOU DOWN?

Your house(relationship) is broken so that it can be built anew with newer better things(new girl perhaps). So that it can be made stronger, better than ever before! That's how "renovation" works!

[BEATING 'HIM+HER']:>> Be a LION. Who the hell needs her?! Seeing her with 'him'?(on fb?) KNOW that IT'S NOT YOU! How could she EVER have YOUR(you+her) kinda fun with some SUBSTITUTE of YOURS? YOU+HER is what you relate to and think is rosy, NOT HIM+HER!

HIM is a REPLACEMENT. And JUST WHO IN THE ACTUAL HE.CK COULD REPLACE YOU?! LOL! HIM+HER is a GIMMICK, a CATCH, an IMITATION! It looks happier, brighter? It's FAKE! IT'S NOT EVER THE SAME AS YOU+HER!

HOW COULD SHE EVER HAVE YOUR KINDA FUN WITHOUT YOU?! LOL! BRAD PITT'S with her? So what?! It's still NOT YOU! It can NEVER be YOU!
SNAP outa it! NOW! People who care, NEVER give up on you! STAY PUT. KICK HER MORE!

[GETTIN A GRIP OVER HER THOUGHTS]:>> Her thoughts are ECHOES. You hear(think) them even after the SPEAKER'S gone. They HAPPEN to you - UNLIKE RADIO CHANNELS! They're like garbage stink, unpleasant & pungent, staying even after the garbage truck's gone. But that's just the quality of garbage! IT'S NOT YOU! You walk past a street with garbage & smell stink! You didn't plan on it! So too, you didn't plan to have her thoughts! It's not your fault if you smell garbage Keep walking, toward fragrance. [SING] MUCH, Get BUSY with things. Her thoughts've GOTTA FADE.

You're JUST fine without her. You still have skin and are breathing. The "breakup" didn't even touch you! You din't/don't EVER need her at all! Trust me. Your self confidence, courage to live fully without her, to show her this, & that you don't care a damn about her, IS success in this dirty mind game!

It was a long relationship? So what?! It's the old houses that're broken to bits to create newer mansions of light, laughter & clarity.

Breathe deep. DUMP HER, at every level. Let her down. Show her, her place. You can do this. After kicking her royally, you have to help MANY who are in the same state(or worse) as you now, & need help. It's ALL FOR THEM. This whole event is JUST so that you come out of it 100% SUCCESSFUL, tell & share your learnings, experiences & help these people. This is (your secret mission), the final PURPOSE behind the whole situation that's in front of you now.
