5th Gen Ipod won'c go back to home screen [Closed]

Hello, my names Heaven and my ipod is just on the clock app and ive tried pushing the home button it wouldn't work. Then i tried to completely turn it off that didnt work either but when i pushed the lock button i had to hold it just to turn it off and turn it back on. But when i went to turn it back on it just went back to the clock instead of my lock screen. Please help?!
