It sounds like your doing great. I would have loved to hear those 4 speakers from how you described it.
Traffic, long waits, extremely loud people always got me angry when I was newly sober (who am I kidding, after a long day they still do lol) but its worth it to be sober.
Descibing the difference from when you went to your first meeting last monday and how you feel about going tomorrow just shows how each week we get stronger, healthier, and happier as we continue the road to recovery!
Keep up the good work
