Car Fund – Please Help !

Hi Everyone, I was recently accepted to go to college my senior year in high school to participate in BNA classing. This was an opportunity not given to many. I went through multiple testing to get into this program and passed with outstanding scores. The only thing stopping me from achieving this education is a car. My mom has been diagnosed with Hodgkin's Lymphoma and now its up to me to earn money for this. Originally I wasn't going to take the test because of this issue, but my mom told me if I were to pass we would find a way for me to earn the money for a car. This is an opportunity I don't want to give up. And I'm frantic that if I don't get a car than I will have to. Not only will this be very helpful now but further down will help me progress in the medical field.  I finally have found a steady job at an auto mechanic shop but don't get paid a whole bunch. Every paycheck I get has been going into this, and now I have decided to look for a second job. I'm trying everything I can to succeed, but having a time limit of 3 months is not much for a reliable car. My college I will be attending is 30 minutes from my high school, and the hospital I will be preforming at is another 45. This is a daily transportation schedule I will have to do. I will be traveling through bad neighborhoods at night to get home from classes and roads in the middle of no where. So having a reliable car is very important. Please help me and my education further grow. Every little bit will help. 

- Thank you, I appreciate all your help.
