Hi Yer, I truly hope that things work out for you and your fam. Those are some tuff issues you have to deal with. There is one thing in your favor and that is the knowledge we have these days of personality disorders compared to even a decade ago. As hard as is must be for you and especially hard for the kids, try to focus on your knowledge of this desease and how much power and control that does give you and perhaps that will help you to relalize you're not so much at the end of a rope..sorta. The kids really need your insite right now to help them get through this even if they don't ask questions, they still need answers.
I feel for all of you and hope for the best. Remember she is not in control of her emotions and can not control them. No matter how hard she tries, the disorder is bigger and meaner then she is and until she gets the "correct" meds for her, and takes them, she will more then likely get worse and become more depressed if thats even possible.
