Welcome to the US of A! I hope your time will be decompressing, and healing, and that you meet some really neat folks at Alanon.
The format of 12 step meetings can feel very strange, and foreign, and almost cold, at first, so be prepared to go to several, and perhaps different ones, to find out the different flavors. You don't need to speak, but if you do, you will often get folks speaking their experience, strength, and hope back about their situations and how they have coped, much like SR.
I hope you enjoy time with your mother, too, as life is very short, and the people we love love time with us!
Let us know how your meeting went, and don't be afraid to take that phone list at the Alanon meeting and call folks to get to know them better. If you think of the coming weeks as a new career in healing yourself, and work diligently with that mindset, you will experience phenomenal personal growth and strengthening!
Welcome again!
