The serenity prayer can help out when shit hits you all at once, by just saying it slowly and meditating on the words and meaning of the words & repeating it, will ground you. It's not like you are saying it at a meeting, you are saying it as if your life depends on it. That God, grant me the serenity to accept the things that I cannot change, the courage to change the things that I can & the wisdom to actually know the difference. By spelling it out, three stages, breaking it down into phases, but said at once.
For me if I'm in a situation where I'm saying the serenity prayer then I'm not in a great mind space, and will usually contact a friend or my sponsor if it's troubling enough.
Tired of the AA cliches' though sometimes those things too will help dial me back into the steps and into the rooms.
I hear women share all the time of 'where they are at in their program's in meetings, and by just sharing shit unrelated to the topic is what the discussion meetings are about. & The great thing is that afterwords no one is going to take you out back and shoot you. Usually people will pull up and tell you to just keep coming back.
AA is the only club I know of that loves you even more for fucking up and making it back to the rooms to start over.
