I felt a sense of coming home when I found the fellowship of AA as well. One man I know described it as "finding my clan". He says that when he has a bad day all he has to do is close his eyes and imagine himself in one of his favourite meetings with his clan and everything seems manageable again. I've tried it as well and it works for me as well.
Glad you got something from it. There are lots of AA speaker recordings which can be useful as well, if yiu feeling rickety and can't get to a meetings too quickly. I use this website (all free and don't have to register or anything )...
