Help my family keep our vehicle

My name is Myrisha Smith, I am 28 years old and I live in Anderson Indiana. Some of you may remember me from telling my story about my experience living in a  transistional housing shelter at the christmas carol last year. I am a single mother of four small children ages 9,8,4,&2. I attend college full time as well as work full time. Last year due to a vehicle break down I had to look for another car to support my family. Because of my credit, my only option to purchase a vehicle with the little money I had was to sign a contract with a loan company and make payments with an extreamly high intrest rate, The vehicle I purhcased was a 2005 GMC Envoy.  As the year went on I had to make a decision to drop hours at work so that I would be able to keep my grades up in school and stay on track to graduate this May. because of the change my car payment got behind as well as other bills. Over and Over I pleaded with this company to give me time to try to get the money and catch up, they would not work with me and told me my car was at risk for repossession if I was not able to make a payment plus the late fees. Once I got back on my feet and had the money to give them for back pay plus late fees, and ask for forgiveness, they denied any payments from me unless I was to pay the vehicle off for 7000. I am here today to ask for help to pay my car off so I wont lose it. My car can be taking from me any day now and I have worked so hard to get where I am today I dont want to fail now. From the bottom of my heart I am asking everyone to help me and my family. we want to keep our vehilce and finally have one we can call our own. Even if you are not able to help I want to thank you for taking the time to read my story. God bless you.
