Try to work in whatever field you'd like to practice in. If it's child advocacy, try to volunteer for a foster care agency, show depth and breadth to increase your chances. etc, etc, etc
Honestly, I don't think you're as poor a candidate as you think you are. Your GPA is far better than mine (3.23) and you and I are in the same score band (152) yet I still feel certain I am going to law school in the fall. I really think that you have a good chance of acceptance. To where did you apply? There are plenty of 4th tier schools that will accept you and provide a good education.
