Sounds like it went as well as it could have, Meh. And you're right....there will be problems....COWs....crisis of the week, bc that's life.
What's also life, is you doing your best and trusting yourself to handle it, without fretting and spinning wheels trying to change it.
Two things about the hearing....
good job keeping things short l, and you're right .....your mother brought this on herself, so your simple truth is now on the record. She's an alcoholic with mood swings.
She demanded.....you responded, against your will, but she gave you no choice. It was a simple calculation, Meh. It appears the Judge understood.
IME, these kinds of expensive humiliations, for the unhinged trouble makers, are the end of the legal attacks....unless it's costing you more money than it's costing them humiliation.
You don't have to explain more, about it, at work. It can simply pass, and be done....sounds like your boss was understanding, and kind about it.
I'm very proud of the way you handled yourself. Feeling barfy is completely understandable....and normal.
Focus on calming self-care rituals, and work sounds reasonable, as well.
