Please help to get me on my feet after my accident

Hey guys, as you know I was in a pretty big accident two days ago where I was hit by a dump truck at 50 miles an hour at a stopped red light. My car was completely totaled and I’m lucky to be here! I’m trying to heal so I can go back to work but insurance said they can only give me Kelly Blue Book value for my car. I’m hoping to find some help to go towards a used rig to get me back on the road and back to work. I’m not usually one to ask for help, but this situation has me rocked and ANY help is greatly appreciated!!
