I can't do it.

I cannot be a mother to someone who wants to make my life a living hell.  I swear if I left the picture she would not even do this shit. Rose is acting worse and worse every day. She is physically abusive, mentally abusive, and emotionally abusive to everyone, Darien and I are the worst. I am suppose to be watching her all week this week. How do I parent her, and my sick 3 year old, and my needy 3 month old?  I can't!
