I guess we dont really know how far back the active addiction goes .She was clearly mentally unstable from the kids being small and made some very questionable decisions even then.Agree she does need help and is unwell,its sad to see ,even though I dont feel sorry for her as I dont think she was ever a particularly nice person or a good mother.Shes obviously surrounded by horrors as well or other addicts.Maybe she has had good people or family who have tried to intervene and given up.Its scary to think how life is going to end up for her and her two girls
