BM, if you judge AA by one meeting, its a bit like judging MN by one post one one thread. Nonsense, as you know.
But more importantly, judging is irrelevent: does it work for you? Can it help you stay sober/alive?
Here's the thing - my first AA meeting I privately thought was a farce: I couldn't believe in a million years that I either belonged or could benefit from sitting in an old Portacabin in the back garden of a treatment centre, with a load of old men (mostly) talking about booze in a way I didn't relate to. I was 25 years old, a cool drug user (ha), wearing black bondage trousers instead of a cloth cap, and couldn't relate to a word they said. My first NA meeting was not much better - they held hands, ffs, were they born again religious nuts or just pretending?? I was scared, but also relieved, thinking 'there, see, I don't belong'.
Luckily for me, I was stuck in a treatment centre detoxing (off some very dangerous combinations of alcohol and drugs) for the first few weeks, and had to attend whether I liked it or not. Not. Eventually, I began to relate to one or two people, and then to hear messages that made sense to me, and then to experience the well-being and opposite of loneliness that came with saying my name, and admitting I was an addict/alcoholic, in front of a whole group of people doing the same thing. I didn't like it, couldn't understand how or why it worked, but work it did.
Twenty years later, I know perfectly well it works, have companionship the like I've never had before, but still don't relate to all I hear in meetings, prefer some to others, etc.
No idea if any of that helps - probably not, tonight, anyway, but maybe tomorrow?? Do'nt wait too long before getting some help - if not AA, then go back to that unit you contacted, or try something else, but get help. The hard part of staying sober is how you feel when you stop drinking - not the stopping, necessarily.
