Keep in mind that EVERYBODY gets their heart broken at least once. It even happened to me when I was about 22 and I always thought I was bulletproof
I remember waking up in the middle of the night calling that bitch's name because I dreamed that I heard her voice lol... sooooo melodramatic....
It's one of the things that makes you more human. You WILL get over it and be a better person for it sooner or later.
