Welcome to SR, DeVon.
Unfortunately, you very well may be fighting alone. My question is...is it really your fight? You mother is an adult and is going to make her own decisions and there's really not much you can do about it. I know it's so hard to watch someone we love going down a bad road, but you have to take care of yourself and let her decide how she is going to live her own life.
Stay strong and take care of yourself and if that means no contact for a while, then that's probably what you should do. It will drive you crazy watching someone you love destroy themselves. Give up your front row seat to the drama and take care of yourself. (((HUGS)))
