It's nice to see that you have a good awareness of what has happened, and how it has affected you. I think you are fairly well positioned for good recovery.
I will tell you that there is, in theory, no such thing as a permanent group leader in Alanon, so it's likely there's a different leader now. I'll also encourage you to not let one event like that disengage you from Alanon. People are people, even in Alanon. Once is an anomaly, several times is a trend.
I'll gently suggest you go back to ACOA or Alanon ASAP, continue coming here, find yourself a new roommate and whatever job will get you by, and restart your life from there. It can and will get better if you let it, despite your mother.
Lastly, take what you've learned from this and let it inform your future decisions. You'll be glad that you did.
Take care,

I'll look and see if I can find an ACOA group though.
