Hi, I'm sorry for what you are going through. The Salvation Army has free rehab. They make the people in thier rehab work instaed of paying money.
In my state, they have something called 'Rule 25" which is a program where you can get 28 days in-patient free if you do not have insurance. Maybe your state has something like this.
Call the United Way, they are in the phone book and on line. They can direct you to resources.
