My heart feels broken?

i'm crushing because i'm crushing and he doesn't know that i'm crushing..."i'm holding on a rope got me 10 feet off the ground" ---(one republic) ...thats how i feel. I'm taking a break from homework for a bit and this was the first thing that came to mind. Its a really horrible. Honestly if I could choose I wouldn't like him to free myself from heartache. How do you deal with uncertainty when crushing??? Girls and guys can answer this.
