Some advice:
You're putting way too much pressure on yourself and attaching way too much significance to this crush. You're so young, dude, and you should definitely work towards appreciating the luxury of time that you have. Once you realize how insignificant your social life is now, you'll actually start having a much better one and be more outgoing with the ladies. Because the #1 ingredient in "cool" is not giving a **** about ****, and this will make you more attractive to everybody.
Do what you want; make mistakes; and realize that at this stage, social failure vs. success doesn't matter at all. I promise, you'll automatically start being more successful. Good luck, man.
PS Make mistakes, but remember to be responsible, for God's sake!
