My Bestfriend's Brother

I was fourteen when I first fell in love with him. He was unaware of my feelings. He was sixteen back then, but now he's twenty and moved away. I was sixteen when that happened and he moved right away once he turned eighteen. Now I'm eighteen and my feelings disappeared after a few months. It didn't bother me at all when he moved away.......okay I'm kidding I was depressed but I didn't show it in front of his sister Kylie. I would always lock myself in the bathroom balling my eyes out. One time I even tried to cut myself but stopped myself knowing I should've moved on and not destroy my skin. His name is Jaden Casanova and he's my best friend's brother.
