Its 5:30AM and im still wide awake! HELP!?

Its 5AM and all iv been doing is tosing and turning and racing the clock for the past 3 hours. Its like when I do start drifting asleep, my mind freaks out because I am going to sleep. Then before I know I'm up and wired with my brian full of things. Iv tried everything and its very frustrating. I just kinda need some kinda of relief that I can go to sleep way more easier and more relaxed so this might not happen next night. Wide awake! HELP!
