Kim, I'm just now seeing this but while I was reading about what has happened in your house and how she has been acting I was thinking to myself either she is on drugs or she needs some phychological help. I see you said she has been suffering from deperession and that a family member is bi-polar. Could she be bi-polar? I don't know a whole lot about it but from what I do know it sounds like the outburst/rage could be that.
