Definitely hockey, as Ash said. It was a really big sport in my life, especially since my brother played on the same team. After I left hockey I was really sad. I didn't really feel that happy when I was watching my brother play the game when I couldn't play because it was too dangerous for me, and I didn't want to get hurt again.
I lost time in school that I couldn't gain back. I lost some of my friends, but definitely hockey was most important because it was such a big part of my life. I'm really sad that I can't play anymore, but it was the right decision for me.
