Hey there! I’m in AA due to cost, also. It’s a great immersive, supportive program. Just jump in and make it your own. People will welcome you with open arms and you will have the structure you need to get sober. Do 90 meetings in 90 days! There is some old fashioned wording to the text (written in the 30's) but the crux of the program is the truth of alcoholism especially the fellowship.
It’s probably a necessary move for you. Doing it on your own or just using the Internet is much, much less effective.
Stay close to this forum on your down time. Best wishes to you.
