welcome, ST, and give yourself some space for things to settle a bit. your brain and mind will be going through all kinds of things, changing, in the next little while, if you stay sober, and so just a heads up for some unpredictability.
as you likely know, AA has a suggeted solution for recovery, and following the suggstions works well for many, including me.
good to see you be proactive, and hope you stick around.
