My sister went through a horrible incident about four years ago which resulted in the loss of her job. She has not been able to get a job ever since. She has totally isolated herself from all family and friends, most of which were there to support her during her ordeal. She is always anry, and critical of anyone around her. She often bursts into tears. We think that she suffers from severe depression, but she believes that it is everyone else who needs help not her.
It is very sad to see her waist her life like this, but how can we help her if she won;t acknowldge her condition?
