"her dislike of you getting into Alanon doesn’t sound cool."
Got to agree with Mr. C as that was my gut reaction to your comment too, tryvia.
Maybe it's because I have just re-read various chapters of "Co-dependent No More" by Melody Beattie.
Alanon is for you, tryvia. It does not matter what somebody else thinks about what you are doing to help yourself. Addicts seek out enablers and seek to control them.
Do what you have to do for you.
