I need to fall asleep?

You seem like you have a lot more energy than most people. Try going to bed later than you usually do. You said that you dont feel tired, even though you dont sleep that much, so there really doesnt seem to be a need for you to try so hard to sleep so much. However, you're at that age where pretty soon all you will want to do is sleep. trust me. Just do whatever feels right for your body.
