A few years ago my dd moved back in with us because she had no where else to go, her car had been repo'd, she was behind on bills etc, etc.
Unfortunately we discovered too late how much she didn't want to be there, quite quickly having her at home felt like a prison sentence for the rest of us. She was unpleasant and argumentative, becoming abusive in her language in general making our lives h*ll. I knew something was hugely wrong, this was not the daughter I had raised but I didn't know what to do or how to do it. One evening she was being particularly nasty, after a yet another fight she grabbed a knife and refused to put it down. She threatened to kill herself and in desperation I called 911. LEO's arrived quickly and almost before I knew what was happening they had taken her away.
I was shocked and devastated, this wasn't my intent but at the same time it was a weird relief, I felt like I'd been holding my breath for 4 mos and now I could breathe, knowing she was where she needed to be. I know this isn't the same as having your child arrested on murder charges. But it wouldn't surprise me to know they feel the same.
