I am sorry about that. I don't know if you have tried this or not. I have had to do something similar with my iPad before.

Press and holding down the power button for 20 seconds or more. Then turn the device back on by hitting the power button again. If this doesn't work the first time, you can try holding the button down for 30 seconds or more. Most of the time, this will be all you have to do to make the Kindle Fire work again.
