Ok sooo... I hit someone from behind with the front right end of the bumper... It's now offset from the rest of the car... It's pushed in and to the right if you're facing the grill. Is there any way I could fix this by myself?

 

We need pics. You can loosen the bolts and move the bumper around and retighten them to get the angle you want.

 

If you crushed the deformable section behind the bumper cover you will need to replace that too.
