Open Question: What does this mean? What is wrong with me?

I can't stand staying away from home. My mom has died when I was 6, and I can't help staying away from home, or at least away from my grandmother. I can't even sleep in my own room, because for some reason I am not able to sleep and I don't feel safe without my family. Now, I have to sleep with my grandmother every night, and even sometimes, it takes me half an hour or even one hour to two hours to fall asleep every night. What is wrong with me? Now I'm dreading college and 4-day long trips with my school.
