i got water damage or something of the sort towards the end of last month but my phone started back up again, i was very confused but after a couple days the screen turned black and is showing me an error “FastBoot mode”, what does that mean what do i do?

The two universal solutions appear to be:

1. Reboot your device to get out of fastboot mode by clicking on the power button to turn the device off, and then turn it back on.
2. Restart your device by pressing and holding the power button  continuously for fifteen seconds.  The device should then vibrate once and restart.
