From what I have read is that she needs to get it out of her system and it doesn't seem like is going to happen anytime soon but unfortunately there is nothing you can do but work on yourself, try and get some sleep, workout even if its 10 pushups a day, read a book, read positive quotes, read the bible go to Psalms, call you family and tell them how you feel, get it out of your system.
You need to take care of yourself to be able to take care of your kids.
