Got into an accident, wheel is literally bent inward. Not sure what's wrong?

I got into an accident turning left, and was struck pretty hard in my rear wheel and bumper. The rear wheel is literally bent inward, the bumper is barely even attached, and the door barely shuts. I figured I have to get a new bumper, and straighten out the body, but any ideas on what's wrong with the wheel? It's not possible to push, it's stuck how it is. I really need to get this fixed, I'm a high school student with a minimum wage job and I pay for almost everything on my own so it's not possible for me to get a new car anytime soon. Any help is greatly appreciated
