Welcome. Like others said, you have to decide you want to be sober- more than you want to drink- and a plan of getting and STAYING sober (not just not drinking!) is key to long term success.
My path is also AA and I have found my thinking entirely changed since I committed to being sober and working my program. There is so much to this world- and now, my life- than alcohol and now I have the privilege of discovering it.
You can do it.
