Gosh that feeling of anxiety and just wanting to jump out of my skin....that was one version of it that I went thru a lot in early sobriety. I'm always one to recommend what I call the Send Myself To Bed Early technique- whatever early means! Or naps.
I was very sick at first so it was about 100 days before I took the tiniest of steps back into exercise. Def something to do when you heal!
It took me awhile to stick around or come early as far as meetings- I even got agitated by the Serenity Prayer and the readings at first....but in time, getting to know people is good- and, honestly, killing time around a meeting so it turns into even 2 hrs of time is something that so many people recommend!
I know these days are tough in a lot of ways, Tetrax, but I am really proud of you for being sober.
