Just a nightmare

Was in a car crash on Christmas eve, rear ended. I was ok but developed acute whiplash. Pain three days later. My car has been in a tow lot waiting to be appraised by the at fault driver insurance. It took over a week and they notified me today that it's a total loss, and I only have until tomorrow to get my things. That they'll only pay until tomorrow.
Then, right after that, I get a letter saying I am responsible for damages incurred. I'm like What??? I didn't have collision so now will need a lawyer that does damage claim in addition to personal injury. I am so stressed and trying to find one in the next day or two. What a Happy New year 😟
