Oh wow. I'm surprised your parents allow you on pills to sleep. You seem too young for such drastic measures. Have you had a sleep study done? Sometimes it's just a matter of clearing your mind before you sleep, getting proper exercise and diet and balancing work and recreation. Have you tried relaxation techniques? Praying? Be sure you unplug from electronic devices at least an hour or 2 before you go to bed at night. The light plus the mental stimulation of something like a phone can keep you awake.
