Washbe, you won't believe this but they didn't keep her for even 3 days. They felt bad for her and after letting her sleep off her stupor they discharged her. I tried desperately, practically begged and they let her go. I live three hours away from the rest of my family now because of my job. It is both a blessing and a curse. I worry about not being able to be there every minute, but at the same time it is a good thing for me and my kids that I'm not.
OTL, I've recently resigned myself to not putting so much energy into trying to rescue my sister, reasoning with her, or trying to get her to stop. She's going to do what she does. My role as of late is to just be there for the kids, to give them a break from their reality as much as I can, and give them big doses of happiness every chance I get.
The support and responses from you guys is a really big help. I can't thank you enough!
