Thanks for the detail.
I had some personal experience with this on the other side. My mom, after a life-long battle with depression, started drinking heavily after a divorce, business breakup and the death of her boyfriend. It got so bad that she showed up to family events and her job roaring drunk. I got calls from the police and from coworkers. We arranged for an 'intervention' and she told us all to go to hell, so, I did my best to push it out of my mind. Meanwhile, she got so bad that her house went into foreclosure and she declared bankruptcy, and had to be admitted to the hospital several times in a state of acute alcohol poisoning. Once I even signed her in for an evaluation at a rehab against her will, but she signed herself out in three days, her legal right. However, every time I had Adult Protective Services schedule a visit, she'd clean up her act, serve tea and cookies and charm everyone with her wit and her sense of humor. "We can't do anything for someone who's made bad choices" they told me!
Imagine my dilemma - I don't want her to kill herself (or someone else, she's still driving) but she will not admit to any problems with alcohol. Finally, at the last near-fatal hospitalization, I am able to get a psychiatrist to admit her to a lock down faciality and hold a competency hearing. It was very ugly.
Today, it's a year later, she is sober (perhaps against her will), her health issues have been addressed and she's on medicare/medicaid and has a legal guardian, and is living in a controlled facility. She is better than she's been in years - I actually enjoy being with her. However, she is petitioning the court to end her guardianship and they might do it, so we'll see. Apparently she's admitted (but not to me) a problem with alcohol.
So, while I am a total liberal in almost every respect when it came to my mom destroying her life I was completely ready to lock her up and at least give her the opportunity to sober up before she died of this. It gives me some hint of what parents might have faced or feared when they dropped kids off at the seed.
