Why am I sleeping so much?

I'm 17, male, around 6'2 to 6'4. This is a normal day for me:

I stay up all night, Midnight until around 7 am, go to bed and sleep until 2pm when someone wakes me up. Even though I've been sleeping I roll over and go back to bed. When I finally do wake up, it's 11pm and I'm still tired and I just want to sleep, but I wake up because that's stupid that I've been sleeping for so long and I stay up until about 7, and when I wake up at 7 I tell myself that I'm just going to stay up all day and go to bed at a normal time, like 11pm, but instead I fall asleep around Noon and now that is my schedule,
