Need help

Hello to anyone and all my name is Sara and I am a single disabled 58 year old woman who receieves 721.00 per month. I have purchased 5 vehicles in the past 5 years and every single one of these vehicles has stopped working within a 6 month period. I purchase a vehicle in March of 2013 which stopped working in June of 2013. I was without transportation until March of this year when I purchased a vehicle that has stopped working in the first week of May. Because my son graduated high school in May of 2013 and I needed transportation so that he could apply for jobs and as I live in a very rural area all the nearest shopping bill pay centers etc. is 18 miles from my home both ways. In addition the only job opportunities are also 18 miles from my home both ways. He applied to one of the local Walmarts (18miles from home) at the beginning of May (2014) and got the job but on the day of orientation May 5 2014 the vehicle I purchased in March stopped working properly. I have had several mechanics look at the vehicle and while no two have agreed as to what is wrong one says I need a transmission and one says I need a transfer case. But regardless both will cost me an excess of over 1 000.00. My refrigerator has also stopped cooling in the bottom (freezer still works) so I need to replace it as well. My son has started his first job and we have no transportation to get him back and forth to work or go pay bills and household supplies. There is a market in my town but everything is priced so hight that in order for me to be able to strecth my dollars I need to be able to shop in town (18 miles away). In addition my son desperately needs to be able to work and become a productive member of society as well as assist me. I don t know how this works but it would be greatly appreciated if someone out there could help us. I do not need money directly to me it can be paid to a Chevrolet auto repair center and to any sotre where I can purchase a refrigerator as I cannot afford to have people take me back and forth to town to shop for food so I try to purchase as much as I can afford at one time but now have no where to keep my perishables fresh. God help me
