Yep, currently going through this with a family member. YOU need to go to AA or NA meetings to learn some coping skills, and find some support. If your brother is depending upon you for things, (housing, transportation, phone) stop. Addicts are superior manipulators, and will say anything to get you to believe they are, or will, or have changed. They will not change until they are ready, and often it is just a tick past rock bottom when it happens. A brush with death, the law, a jail sentence... something. While interventions make good nighttime TV, if an addict isn't ready for change, an intervention, I M O is not likely to make things better. Encouragement and support for recovery are always necessary, but pointing out the lies, the habit, and dogging the addict aren't going to help. Chemical dependency changes the way the brain works. Once the addict is ready, there needs to be medical intervention to guide the person back to safer ground, or a relapse often occurs. Really, AA or NA for you and your family is the best place to start. I hope it gets better for you, I really do. Things like this can make a family unravel at the seams.
