This was my son a few years ago. You will need to live in a place where you don't need a car. Couch surf with loved family that you choose to bring into your life. Find a spiritual teacher who can be like a father to you. Apply for benefits of some kind. At least food stamps. Find someone who needs you and your gifts. Then looking for a job should be a later priority. You need to learn to be good and nurturing to yourself first.
