Gee, sorry your evening was upsetting for you.
I hope you and your daughter can patch things up-- that is if the arguement was between the two of you-- I mean. Hope the atmosphere in your home feels less awful real quick.
Not sure if you thought about this but, I think it's really something that your mom was sobbing and said she was sorry. Some people never are accountable for their hand in someone's abuse, seems like this is a good direction that your mom has taken with you. (I've confronted my mom and I'm always in the wrong, it was all my fault- for the various abuses that I endured, or I'm making a big deal out of a little thing-- like being held at gunpoint is a little thing.

, and her chaotic temper was the child's fault, ....so I won't even try to confront her anymore-- it's just not worth the upset or energy.

-- she does NO wrong)
I hope you understand that I'm not discrediting what you're going through-- just that maybe there is a little ray of hope there....?
wishing you peace--
