I'm 15 years old and often have a lot of trouble sleeping. I try to have a consistent schedule, but some night, usually a few nights a week I either just can't fall asleep or wake up after a few hours and can't sleep. The worst part is that I'm so god damn tired on these nights that it's stressful and I hate my life because of it. I'm writing this at about 1:00 am after trying to sleep for a good few hours. Please help.
