Rear bumper/Rear pannel question(cosmetic damage)
 

Someone backed into me, Im trying to get my car in proper condition immediately. I was afraid that my rear axel or frame had actually been damaged, i spoke a collision specialist and he said i needed a new Rear Pannel,
Now my question is, My rear pannel seems to be directly connected to the fenders above my rear wheels, therefore it looks like the pannel is connected directly to my cars outer body. I dont see how i could remove the rear pannel at all.
If you have an experience with this Please let me know, im attaching pictures so you guys can get a mental image.
my question is located near top right, where the headlight covers, the pannel is connected to side of the car, how do i take it off? If you guys can point me in the right direction or to someone who has dealt with this issue, please let me know i need to get this done so i can drive to work, ASAP, THANK YOU SO MUCH
