AS I'm sure you know by now, postpartum depression (or even psychosis) can be a serious thing. I read a story in a magazine yesterday about a woman who suffered postpartum psychosis, left the psych hospital she was in, and wandered the streets for a few months before her H found her.
There are probably biological reasons for this - hormonal or nutritional. Thyroid problems are common in the postpartum period and may be linked. Nutritional deficiencies may have developed during pregnancy - B12 deficiency, for one, can cause depression or psychosis.
You're in a tough place right now, since she will be looking at you as the enemy. Does she have family members who could help her to get treatment?
Stay strong - you know this is a mental illness right now. Take care of your kids and do what you can to get help to her.
