Hey been there and doing that except one thing be persistant, look on craigslist, and think about getting a reliable roommate, people are allways wanting to share.
Prayer helps too and there are local agencies willing to help with deposit and rent, goto food banks, and be humble, churches help too, plus their is low income rent for people with disabilities that goes bye your income. I get up early and check the newspaper, I drive around sides streets and look for rent sighns I write down the number and call and I pray some more finaly I am getting a whole house to rent near stores and parks. Have faith and don't give up!
