Insurance Won't Cover my Car Accident

Hi, my name is Dean Garner, I am 18 years old and this is my story. In November of 2021 my father broke the family and left. Long story short, my parents are now divorced and he left, leaving us with bills that we can't afford. I've been working at Olive Garden for almost a year now and am currently a server. Along with that, I Doordash whenever I can to make extra cash to help my family.

This is where Doordash comes into play. On Thursday, March 10th, I got into a minor car accident while trying to complete a Doordash order. I was labelled at fault when I wasn't - in short, the car in front of me braked suddenly causing me to follow suit. The car behind me then rear-ended me with enough force to push me into the car in front and proceeded to drive off while the person in front and I pulled over. Today, I found out that my insurance company will not pay for any of my damages as their fine print stated that they will not cover any damages associated with business use. I went to Doordash to see if they could do anything to help but they haven't gotten back. This is my absolute last resort. I am not going to spend money repairing my own car, I only need to pay for the other cars damages which came out to $5000. Anything helps and is greatly appreciated.
