Help Me With Transportation!

Hello! My name is Justin and I am a 4th year Social Work student at The Ohio State University. In the picture is my beautiful, awesome diva of a Mother that raised me into the Man I am today. For years my Mom has been struggling with a disease known as Scleroderma which is an autoimmune disease that attacks the organs inside and out. A couple years ago, I was involved in a terrible car accident that completely totaled my car. Since then I have made my best to save up again for a new car but unfortunately, with school, and my mother being ill, I have not had any success reaching my goal of a new car. Recently, my mother has been severely struggling with her health and I need some type of vehicle to travel back and forth from Columbus to Toledo. My mother is very very close to me since I am her only son and she is not married. I promised her that I would graduate on time in May of 2018 so she can see me graduate from college. The distance is troubling for me and as a broke college student as I am doing everything I can to make bus trips back home to see her. If you could help me out in my mission to get a car this would make traveling so much easier for me to see her. I personally am struggling with not knowing the amount of time she has left and I want to make it as convenient as possible to see her. All help would be greatly appreciated on the behalf of myself and her included.
