I’m touched by your story clara beth. I want to offer my warmest encouragements for your journey of recovery. It sounds like your family has a long tradition of alcohol use. Some traditions are meant to be broken.
Just two thoughts. First of all regarding your brother. You are not responsible for what he does, pure and simple. You might FEEL responsible, but this does not make it so. Let yourself off the hook.
Second, I believe you have a lot to gain from AA. I would consider calling the closest AA central office and seeing if they know of someone to hitch a ride with in your area. Here is a link to phone numbers in Montana. Just call and see what they suggest.
