Need a car to find work

Hi I'm right now on disability. I am there because I have made some mistakes in my life thought I didn' need to take care of myself or my health well I was wrong. 4 years ago do to poor diets and a severe depression I had a heart attack. My weight was 365 pounds I have only lost 20 pounds so at 345 pounds I'm still not able to stand for a long period of time or work were I have to go fast. The only job I can do at the moment would be a parts driver or a delivery man but I need a car. Welfare only allows me to have a car of under 5000 and I believe 10 years old. That is y I'm asking for at least 2000 dollars so I can get a car and be able to get a job so that I can support myself better and be able to give money to my ex to help pay child support. I love my son and it hurts me not to be able to help pay his way. Please every bit helps... If I can raise more I can get a better car or if someone has a old car the is under 5000 dollars and wants to give it to me to help I'd really appreciate it. Thank you from the bottom of my heart
