I have terrible insomnia, please help me...

I keep trying to get nine full hours of sleep, since I'm in school now. It's not working out, I go to bed and read at 8, turn off the lights at around 9 or 9:30, but then I just wake up at around 11:00 PM to 1:00 AM, and by then it's super difficult to get me back to sleep!

I've tried taking a melatonin before reading, and it makes me feel sleepy faster, but I am still waking up at 11/1.
