Why I can’t fall asleep and why I can’t get up

I usually fall asleep around 10 or 10:30PM.  I know, that’s pretty late for a kid of my age but I just can’t fall asleep.  And, of course, in the morning I can’t get up early.  Generally, I need between 10 and 11 hours of sleep so it is hard for me to get up before 9.  Needles to say that I am always late for my school and I am really lucky they haven't yet kicked me out.  I had numerous conversations with my parents and we are really trying hard to solve this problem.  Finally, I came up with a pretty good explanation: 

  “My bed is really hard in the evening and that’s why I can’t fall asleep.  And in the morning my bed is extremely soft and then I can’t get out of it.  And especially when it rains outside my bed becomes even softer.“

Zasto ja ne mogu da rano legnem i rano ustanem?  Zato sto je krevet mnogo tvrd kad ja legnem i mnogo je mekan ujutro ... a narocito je mekan kad pada kisa i onda ja ne mogu da ustanem.
