Why can't I fall asleep?

It's 7 am and I haven't slept. It's driving me crazy! I have to wake up at 10 to go on a trip with my family so I Planned to go to sleep early. I have been laying in bed for I don't know how many hours trying to sleep! I am exhausted!! I tried everything I could think of. I tried to lay completely still hoping I would just fall asleep. Then I tried to listen to music to relax. When my dads alarm went off at 6 I knew I was screwed. I thought if I held my breath a lot I would pass out then I would just start breathing again but stay asleep.... Obviously that was a stupid idea. Then I started twitching and I started sobbing! All I want to do is sleep!!!! I thought of maybe waking up my mom to ask for help but I don't want to wake her up. I'm only 13! Why is this happenin to me?! And now I'm hungry! Which is weird because I don't eat breakfast!
