No Electric and huge loss of power after pothole

So I was driving home today and hit a pretty bad pothole. Afterwards all the electric inside the car besides the radio went out. Gauges were stuck, no A/c, no blickers, can't even lock the car. But windows still did work. Then as I slowed down I realized I had barely any power at all. The engine was revving up slowly but no power to the wheels. Once I got home I disconnected the battery for 20 mins, then plugged it back in and still no change. I tried to start the car and it took a bunch of turnovers and it barely started, almost conking out.

Anyone know what this is? I do have a JB4 in the car so Im hoping that didn't do anything.
