Hello! Andrea is a seriously mental ill! It is not a very happy ending for her and all of us too. it is very very sad at least she gets help at the hospital. Russell is also the responsible. She left many clues of her mental instability and her husband pressured her to deal with something that was went over her head. In my opinion, Russell should have been partly responsible for the very sad situation. Her husband ignored the psychiatrists' advise for the mother not to get pregnant. He forced her to homeschool the kids while being sick, etc. He pretty much abandoned her on her own and a unfortunate tragedy happened. The real victims were the kids.
BTW have you heard of the Post-Partum Depression? if not ... You should read this info --
Depression after pregnancy is called postpartum depression or peripartum depression
