@inkiii this "glanced at the charge button, and it said 0" and the subsequent failure at a later time suggest that your Fire either has a depleted battery that no longer accepts a charge or you are having an issues with the charging port or power management IC circuit on the motherboard. I would start by replacing the battery. Use this guide [guide|61736] for that. That will at least give you a known-well starting point should further troubleshooting become necessary.
