Sorry if I'm totally off base, but I don't think sobriety is the issue here...it's your sense of helplesness in changing/lessening the chaos swirling around you.
There are so many factors out of your control, they're mind-numbing. I know that feeling, really, I do. That feeling is no excuse for checking out and/or succumbing to the maelstrom. (Not that I think you're checking out or succumbing--but one can only take so much before shutting down, and I sense you're nearing shut-down-mode. )
Where is your center? Who are you when you strip away the obligations and busy-ness and fatigue? Who do you want to be?
