Alienation
In psychology, alienation is the condition of being separated or marginalized from other individuals or some larger segment of society. This can refer to a psychological or emotional separation between parent and child, a physical separation between a child and an estranged parent (such as after a divorce), or a person's social separation from a greater aspect of society. There is also a condition known as parental alienation syndrome in which a child will insult and belittle one parent, frequently at the behest on the other parent, or for reason purely of their own.
