Staying at Home for Several Days

I used to sleep really late like at 4 and even 7 am because of reading fanfics of harry potter, Avengers, Attack on Titan, Ect. And I got so tired to the point of not going to school for a few days or maybe take a day off saying I wasn't feeling well to not go to school. I would sleep until the afternoon and luckily I don't do that anymore, but I still sleep late. (￣∇￣")
