When I was 12-13 I used to have trouble falling asleep, since I'd be thinking of anything stressful from the day. I fixed it with a form of meditation - thinking about nothing was impossible, I forced myself to think of fantasies when I'm trying to go to sleep instead of anything real. It has worked well for me for 20 years.
