Can this be a sleep disorder? Can you have a sleep disorder?

Well. Im only 13 but I have GAD which is Generalized anxiety disorder (its when anxiety becomes serious/bad) I also have O.C.D from which I always am afraid that doors arent locked. These both tend to keep me up at night for along time. I'll be up to 1:00 in the moring. In the moring when I need to wake up at 7:00 I cant. Its starting to scare me. My dad says that I always respond when he wakes me up. But yet I cant remember a thing. I dont even remember being waken up! Even if Im physically woken up! Sometimes I do notice Im being woken up, but I fall (and not purposely) right back to sleep without relizing! Then when im actually up I feel fine the rest of the day. No one believes me though! I tell them and they keep thinking I do this on purpose... I dont get it. Have you ever heard of something like this? Sometimes I even respond and say things like " Im getting up now" or "Give me to minutes". And, if someone wakes me up by pulling the sheets off me, I was told I would get up and tell the to "Stop it." I dont know why? Is there a name for this. And, I dont think Im sleep walking. This happens almost every morning!!!! please help.
