An otherwise happy, healthy individual who has quite suddenly become withdrawn, angry, aggressive and sits by the window most of the day refusuing to see anyone. Just staring out in silence. She looks so unhappy and blank it scares me. Her husband and children can not understand. She won't get help.Is there anything on this Earth i can do for her? Its as if she's given up. Won't eat. Won't sleep. What the hell can suddenly cause this to happen to such a wonderful person? And no, there is no debt, no marital problems and no ill health. She has it all.
