Once you sober up you see who your true friends are. When you get clean they don't call you anymore. You try to hang but it's not the same. Alcohol was the only way you can bond with this person. They made you feel guilty for not drinking but they felt bad because they were drinking. You respected one another's decisions and departed. Once you get clean you feel empowered not to be self destructive but become more creative not so angry finding other outlets for misplaced aggression.
After while you find courage to do what matters no more liquid courage that gives you false hope no more waking up hung over after a long night of drinking till you black and don't remember what happen or hearing about all the crazy you did while recovering from a hang over.
Stay clean and sober clarity of mind no going back not about that anymore. The right people stay while all the wrong leave you.
