I Can’t Go To My Home Screen Or Go To Any Other App On My iPad.

I Can’t Get To My Home Screen. I’ll Press The Home Screen Button And It Just Doesn’t Work. I Can’t Get To Any Other App Either, I Can’t Even Turn My iPad Off Fully. I Let My iPad Die And It Let Me Off, Then It Stopped Working. After Awhile, It Stops Letting Me Move The Screen. It Lets Me Use Siri But Nothing Else.
