Help this teacher get “on the road again!”

My name is Kelly. I am a 50 year old music teacher in emergency need of a car. I have recently become disabled with bone on bone arthritis in both knees. After 27 years of teaching, I’ve been assigned to multiple schools to teach and taking Lyfts and Ubers multiple times a day will be something I can’t afford. I have spent my life helping others and I could really use any help right now to get through this extremely difficult time. I Anything would help, thanks so much!
