Hey littlesoul,
Sorry to hear the anxiety is running high. I think you've got some good ideas going and maybe a little too much excess.
It's good that you're looking at the immediate time ahead, and that you recognize that going to the store is a subtle drinking urge in disguise. As for surrendering to God and embracing suffering... if it's not working for you, just stop. You can't force these things to happen. Maybe you will in time, but for now don't overwhelm yourself.
And keep in mind that early sobriety (even later) is always ping ponging between wanting to be sober and wanting to drink. That indecision confuses ever alcoholic and drives us crazy. You seem to recognize wanting to drink, accept that, don't try to erase that thought, and don't act on it for the next hour, then the next hour, etc.
And AA is also a good idea. There are 7pm meetings in Sterling Heights and Mt. Clemens.
Alcoholics Anonymous General Services of Southeast Michigan - Area 33 if you want to browse more. You can just go for today. You wont have to join, you wont have to talk. But hearing other stories and seeing alcoholics in recovery might give you an inspirational boost.
