Hey there.
Guess what? I know how you feel. I too am learning about Macs everyday, and I have learned a lot about them in my life.
Now, don't freak out, if you still have the force trackpad and the keyboard lit up, you're in good hands. The Mac is still fine. My recommendation first of all is to reset the NVRAM, and then connect the Mac to an external display. That way you could tell if the internal display cable has been damaged.
Do you have FileVault enabled? If so, reset the NVRAM, connect the Mac to an external display, power on the Mac, wait 10 seconds, enter your login password, and hit the Return key. That will boot the Mac.
We can test the Mac after this: best of luck!
