I can't wake up in the morning anymore? Ever?

I can't wake up on time for school anymore. I've tried going to bed very very early, sleeping in different rooms, different temperatures, and I have an alarm on my iPod, old iPhone, Galaxy S3, and iPad, plus a small alarm clock and a large alarm clock. They all make different sounds. I can't wake up anymore on time. I end up waking up at about 11 and my school starts at 8:20. I have even tried going to sleep at 7-8 for a week. That actually made it much much worse. I woke up way way later and was still very very tired. What can I do? I have over 20 absences in my morning classes. I don't have any idea how I'm not getting in trouble with the school for this.

Atop smoking weed! Ii!

Get tested for alergies.

Uhm… Go see a doctor! Like, RIGHT NOW! That really doesn't seem healthy!
