Need help about a crush

[Tesserax]

Alright so I had suspicions for awhile, but it was recently confirmed that my crush is in a long-distance-relationship. I didn't expect it to, but the revelation hit me had and it's really eating away at me. I asked her best friend about it and all she could really say is to accept the fact that it's been going on for awhile and hasn't ended, and to try to get over it. I know I need to do this, but I just can't for some reason.

Every time I think of the situation I just feel a knot in my chest, and it's really tearing me up.

A little bit of info just to give the situation a little bit of context:
We go to the same school
We're good friends
Found out on Halloween when we played a little truth or dare and both "secrets" were revealed
Her crush/boyfriend (it's complicated, I'm still not entirely sure what the relationship actually is) has been away for about a year and came back once, and they were apparently "really good [with each other]" in that short period, and I'm not sure what that means (original quote: "we were pretty/really good", something like that, gosh darn memory -.-)

It'd be great if I could get any advice/help from anybody, thanks in advance if anybody can help :/

Note: I've hear advice from all places saying stuff like:
Let her go!*
Keep her out of your life!*
Love yourself!
Surround yourself with friends!
Remind yourself of all the bad things she did to you!*

The the stars show the ones that I can't really do, because one I've never been in a relationship with her (or anybody else for that matter), two we go to the same school and we're good friends and I'm not letting this petty crush ruin that, and three she has done nothing wrong or bad to me, she is basically an angel, I have searched my memory for everything bad about her and I can basically find nothing lol

The other two I am already doing/trying to do, but it's not exactly the most effective

I'm hanging onto the lose hope that it will end, and I can't let go for some reason. It's like I'm on the end of the rope, and below me it's really dark and I feel like if I fall i'm going to die, but I know that right below me is water but I don't want to, just in case there isn't.

Again, good help and advice is much appreciated, thanks guys :/

Note:This is a re-post of my original, as I posted the original quite late and I don't think many people would've seen it

Every woman is different; if they were all the same, you wouldn't be interested in this one in particular, now would you? I have been in the same situation, and everything turned out perfect, then not perfect, but thats a different story.

Ok well here is what you do...

1# you say your friends right? then you probably have common interests. Talk about these interests get closer to her, but don't cling to her; have your own life but make her a little-bit part of it

2# Keep yourself well groomed and in shape. If you want to get a woman to like you, basic cleanliness and appearance are extremely important. Girls notice things like bad breath, flab, body odour and greasy hair before they notice that winning personality. Give them a chance to see your good qualities

3# Make her laugh. Telling jokes or funny stories is a classic way to make a person laugh, but not the only way. Be bold and think of some antics that will make her laugh, like clowning around. Find out which are her favourite comedians, funny movies, or sitcoms. Watch them with her. Tell her to dare you to do something or even better dare her to do something.

4# Girls don't just fall for random strangers. (Well, some do, but the relationship never goes very far!) be friendly to her in a non-invasive way. Get to know her better and hang out. Every time she walks into the room, smile and wave at her. Sometimes this is all it takes for a young woman to notice you. At the same time though, don't do this too often; It will just end up looking like you're obsessed with her. If you're worried, greet some of your girl friends as they enter, too. If she doesn't seem to see you, when she walks by, just say "Hi _______," in a friendly way, but don't interrupt the class or any conversation she's holding. If she's shy, she might just smile back, so don't take this as a sign that she doesn't like you.

5# Flirt. Being flirty will help keep you out of the friend zone because it will remind the girl that you're attractive as well as a good friend. When you see or meet a girl you like, make brief eye contact and smile. Strike up a casual, flirty conversation and see how she reacts. If you avoid her eyes and act nervous, she's going to go into overdrive working out what on earth you mean. Girls react mainly on body language and emotions. If you make them feel happy, they'll see you as fun and caring. If you creep them out, they will get nervous. Don't put pressure on yourself or her by thinking of her as the girl of your dreams. Try not to stress about what will happen if you make a bad joke or say the wrong thing. She may be just as nervous, and small mistakes will likely go unnoticed or will simply be ignored. Don't worry if flirting seems difficult at first. The more you talk to girls, the more relaxed you'll become.

6# Compliment her. If you really like someone, you probably appreciate a lot of things about her. Why not let her know? If anything is different or new (her hairstyle, nail polish color, shirt, etc.), make note of it. The more unique the compliment, the better received it will be.

7# Impress her. There's no one-size-fits-all solution here. What impresses one girl might make another roll her eyes. Your best bet is to be yourself. Demonstrate a unique skill, talent or something difficult to do that you're proud of, something that sets you apart from the crowd. Not only will this make her feel good about you, but it can boost your confidence, too.

Aaaaaaand that should work, if it doesn't then meh, i dont care. :)
