Like others here, I've been there. It sucks, plain and simple.
Think about your sobriety like that football game. There's no need to start throwing desperation passes and hail mary's right now - this is your first possession. Run some clock, establish the ground game, don't hang your head on 4th down.
Things will perk up, but these early days are very tough in their own way. Stay true to yourself right now and don't pick up a drink, and don't go out with your drinking friends. Tomorrow's Sunday, you can get through this and the sledding will get easier when the week arrives. Good luck.
