I understand. I was also fast-talking, anxious, hyper, nervous.
It was miserable.
I'd say I've calmed down 99%. A lot of it is learning to deal with life's stressors without using alcohol. Letting go. Acceptance. The Serenity Prayer. But most of it is physical, IMO.
I had the Serenity Prayer on a continuous loop in my head 24/7 for the first three months of my sobriety. That anxious horrible energy does dissipate.
You say you want to return to God. I say that is the reason I am healed. Prayer is the single most important thing I do. Full stop.
I don't go to church, I don't go to AA. I do pray. I believe there is a Higher Part of Me. The part that instinctively knows what is best for me. Call it God, or call it Spirit, or whatever. The word isn't the thing. When I seek that, everything falls in line. Ask and see what happens.
I know you'll figure this out. Stay centered.
