You mentioned many things in your post. And asked many broad questions.
You mentioned moving. Possibly moving in with your parents.
You mentioned selling the car? How much is the car worth now? Realistically?
You also mentioned on what to spend the car money on.
You need to find the answer to EACH of those, and work backwards.
Without knowing the whole picture, such as your debt situation, what you were making/employed as, and where you are trying to go its hard to say anything definitively.
Have a serious conversation with yourself, about what you want 3 months from now, and what your goal is a year from now, and form your answers around that.
If you are close to broke, I would say sell the car. You don't live in the middle of nowhere, at least there are buses and you could take them if need be. If you can survive for a little while, why not get a part time job to at least cover your costs.
Again, it's hard to answer any questions specifically without more information.
