Genie,
welcome,
and good on you to wanting to stop.
what helped me after a gazillion tries was to get involved daily in a recovery forum (i used LifeRing), reading lots, going to face-to-face Lifering meeting once a week.....in other words: engagement, a "daily do", connecting with others.
yes, of course you can go to AA; the only requirement is a desire to stop drinking.
you'll know if you have that
you will not have to speak, can just say "i pass" if the chair asks if you want to share. you do not need do anything you don't want to do. that some might come to you and suggest you get a sponsor and do the steps....wouldn't be unexpected, seeing as that is what the program is
this can be done in different ways, but it does seem to help to really get involved.
best to you.
