You are not a failure!! You are an alcoholic and you want to change. That is the important and crucial thing here.
I had to make some big changes when I first quit. i had to avoid those places and people that were a part of my drinking days. It would have been impossible for me to carry on going out to pubs with my usual crowd, the pull was far too strong.
Maybe you need to stop the dancing for a while. Have you spoken to your husband about how difficult it is for you? Are you following a recovery programme?
Remember you are not failing, you are just beginning x
