Although I don't believe it is a 'holiday' down under, please remember no one can be upbeat and happy all the time, and sometimes when one person in a meeting is down, others will zone in on it and report their 'worst' also.
You did learn something though. How NOT to be, lol How you don't want to be. How even though there were folks having a hard time or feeling depressed, they DIDN'T FIND IT NECESSARY TO TAKE A DRINK. There is a message in every meeting as far as I am concerned.
Keep checking out different meetings until you find some that give you encouragement and hope.
Love and hugs,
