Single mom Lyft driver, needs new car

I'm raising money to get a new/used car so I can continue being a Lyft driver. I finally found something I can do to support myself that allows me the time to spend with my 2 ADHD kids. They have spent their entire childhoods in daycare and afterschool programs, and while they were relatively safe, they need the special attention from their mother to learn how to navigate life with their unique gifts/challenges.
As my daughter begins high school, I know this is the last chance I will have to help her deal with the social/peer pressures that so often lead to depression and worse with kids who have special needs.
Our car is dying, I need a new/used one, preferably a Hybrid, to continue ridesharing to support my family. Any money raised will go toward keeping the car running, but the ultimate dream is to be able to afford to purchase a car better suited for ridesharing.
