When I was in high school, I dated the same guy on and off for most of it. They were the most painful 3 years of my life, and to this day I have never experienced such intense or prolonged mental anguish as I did then. Seriously, I think nothing will ever fuck me up as bad as that did. That said, I never think of that dude anymore, and the people I date now aren’t even remotely like him! My point is, you will survive. Go, travel, be heartbroken in a different country, be heartbroken at home. Cry to loud, stereotypical heartbreak music, and savor the moments of brightness in between. I can almost promise it will never be this fresh or bad again.
