I'm really sorry for what you and your kids are going through.
You mentioned that D14 is on AD's. I can tell you that my youngest D is on AD's and the 1st one didn't work well. Just something to keep an eye out for. Is she seeing a shrink for the AD's or were they prescribed by her Pediatrition?
My D has gone into crisis (cutting, suicidal ideations)and I know the stress of what your going through.
The last time my D went into crisis, I let H know with basic details (ie: cutting, suicidal) leaving him to ask any questions if he chose (he didn't). I made sure he had her Counselors phone number so he could call her for any further info. After she started see a shrink also, I don't think I did give him her number. I would if he asked and he knows D is on AD's.
There isn't much you can do for you xw. It's nice that she asked you what you thought she should do. Personally, I would have told her to contact the Counselor. I know that I may sound heartless about this, I'm not. I understand the anger that can build up behind all of this and how easy it is to spill over, not helping anyone esp your D14.
How is your son taking all of this?
That you are there and really present, will make all the difference.
