An enormous task? That be your Alcohol Addiction Pleasure Monkey talking again.
"Pssst. We can't do this! This is HUUUUUUGE! A Sisyphean task if there ever was one. EY yi yi! It is terrifying! OH NOOOEESSSSS!"
You know better. You know it is as easy and simple as opening your hand. All the thoughts of future potential difficulties all come from beast. And the way to separate YOU from IT, to separate your thoughts from the thoughts of the beast, is to make, or remake in this case, that commitment to life and to you and your future.
There doesn't have to be any catastrophizing, you know that is all beast. In fact, absolutely ZERO badness will happen, and only good, life giving things will happen, many of them the very instant you make that decision to declare your freedom from alcohol .
Are you ready, Tatsy? Open your hand, step through the door into the light. It is all there for you.
