help with staying up later?? (is this the right category)

ok.. I'm 14, and my parents are strict mothafuckas. 

my problem is, I have a broken door that is hard to open after being shut, and I have to be asleep at an early as fuck time (9;00pm est), even though I literally, under any capability, CANNOT fall asleep at this time. 

they get on to me for not doing so, threaten to take away my remote if I don't follow their rulses, but I have insomnia, and I have no source to help it. I can only go to sleep when my body finally gives way and LETS me be tired and rest. my parents wont listen though. 

is there any way I can even get it across to them this is impossible for me? if so, what do I tell them? (they are hardheads and very stubborn, so if you have any ideas please bac it up with immense evidence.)
