When I wake up in the morning, my eyes are painfully filled with sleep?

Tweet

I cannot open my eyes in the mornings until I rub them downwards like 10 times because they are filled with sleep. I go to bed at 9:15pm and I'm 11 years old. I usually cannot get to sleep until 9:45/10:00pm. How can I get to sleep quicker and is tiredness the reason why my eyes are filled with sleep in the mornings because it happens sometimes when I went to bed at 9:00 and sometimes doesn't when I go to bed at 11:00 (if there's been a special occasion). Is it because I wake up automatically for school at 7:00am?
