Chromebook will not turn on and I am PANICKING, please help!!

It is fully charged, and when I try to turn it on the light is shining but the screen is black. Here are all the methods I've tried so far that didn't work:

-Turning it on and off

-Pressing the power button on the side and the refresh key on the keyboard

-Closing the lid

-Pressing the increase brightness key

-Gently patting the screen and kindly asking it to turn on (I'm desperate)

My Chromebook does not have a power key on the keyboard; instead, it has a button on the side that turns it on and off.
Any help would be greatly appreciated! D:
