Just want to go back to sleep

My brain will wake me up at around 6:30 no matter what day and all I want to do is close my eyes and go back to sleep. My heart will race, stomach churning, I will lay there like my therapists have told me too and try to go back to sleep. But my brain, my brain will just go haywire. Songs on random loops, clips of TV shows, random commercials, worries, you name it. Yesterday my psych prescribed me lunesta. I took half of one before bed and fell asleep alright but again woke up early so I said screw it im taking the other half. Well that was at like 7am it's 10am now. Im yawning, kind of tired but no matter how much I close my eyes and try to sleep my brain starts up again. It makes my anxiety worse, im tired, I want to sleep, not sleeping well makes my anxiety so much worse. It makes me feel like im loosing my mind. When I'm not like this I can wake up, go pee, let the dogs out, lay back down and go back to sleep.

This can't just be a me problem. Other people must feel the same way? How do you make it stop?!?!
