I am sorry to hear that you are having this issue.
This is usually caused by a glitch in the firmware and can be resolved by a forced reboot, then your kindle will work normally again. Slide or press and hold the power switch for 40 seconds, then release.Please let me know if this does not work.
Did that work for you?
