Look dude, I had my heart broken too at sixteen, it has to happen to everyone at some point in one way or another throughout a person's life.You're young, there will be many obstacles you will face as the years go on and I promise you that this is not shit. Harsh reality, she isn't into you. So forget her. Get mad about it if you have to, but stop obsessing and feeling sorry because you will only hate yourself later when you realize how stupid this is. Don't waste your time on people who won't even give you their own. None of this will matter to you a year or two from now, let alone the rest of your life.
