Stuck on start up screen (apple logo)

So a couple of days ago I managed to drop my computer somehow, hit the left side of the computer and managed to bend the charger in the process as well (it still charges just fine). At first, the computer was working, just running really slow. I shut it off before going to bed and the next morning when I tried to turn it on, it didn't get past the logo and the spinning gear. I've tried starting it in safe mode and resetting NVRAM/PRAM (neither did anything).

What should be my next steps??

Thanks!
