My parents don't support me going to college but i don't have a job..help?

Okay, im 20 years old and am currently going to a local college. My parents are paying for me to go to school as of right now but they always tell me i should drop out because it's too much stress for them. I really don't want to drop out but if theyre going to stop paying for it i have no other choice. I don't have a job because i dont have a car.....are there any options that would help me continue to pay for school? I dont have any credit so it would be impossible for me to get a loan. My GPA is around a 3.5. Thanks.
