This is why these forums are so great you get such a deverse range of opinion.
I read the story ...looked at the history ..not knowing if the children are prone to the dramatic but assumed that not to be the case because the parent wouldn't have been concerned enough to write the thread. Given the time and the continued emotional outburst clearly the kids are suffering...the op thinks they are suffering and looking for some guidance. I saw kids having there worlds rocked every so often ....looking for stability.
What you got was the full spectrum ...stop ...the kids mental health come first...moderate..... look into professional help ....to ...tough shit adults come first ...spoiled fucking brats shouldnt run your private life..... no room hysterical behavior in this house hold. God damn kids these days. Tough love.
Good luck. Let us know what happens.
