I am certainly not judging you, hon. I completely understand how you are feeling about the meeting and their statements about God. I am of the belief that the only way an addict/alcoholic/codie is going to stop is when they have had all they can take and make a conscious decision to get help. Some people may want to say that is God at work, but it doesn't matter to me if it's God or the guy who runs the barber shop. The fact remains that they themselves have to make the decision.
It sounds to me like you are just doing what you have always done. You take care of others. Maybe you should be a nurse.
But, seriously, if you are to get any peace of mind or serenity, you are going to have to make the decision to take care of yourself at some point. Not just that, but you have children who deserve better. If you won't take care of yourself for yourself, please do it for your kids. They don't have a choice on where they live or what goes on in the home. You do.
