Your W has literally hit the proverbial "Rock Bottom". She is a walking china vase right now and you need to just let her be.
If she needs to talk, just listen. No advice to her unless she flat out asks. Just leave her be and let her feel safe. Just shut up and listen.
After a few days suggest to her getting help with the Bi-Polar meds; she is going to need therapy for the abuse; and then a little later down the road, retroville(sp?).
SLOOOOOOOOOOOOOOOW!!!!!!!!!! Very slow 9. Proceed with caution.
