I'm looking for some of the options for treating my mother in law. Due to some past experiences she was showing signs of depression and over possessiveness towards her loved ones. She hates all women outside her home and reacting so badly when somebody comes to her. We are so tensed with her behaviour. Earlier they tried to treat her but it was in vein. Does she need some psychiatric treatments? It has been around 30 years she possesses this kind of behaviour. What we can do now.
