I am working with a man in a state of depression. Some people tend to say he or she in the situation is a nature of dependence on somebody. It is case by case, but we need to keep in mind that he or she is struggling to deal with the disease.
From a view point of a profession, we need to move on no matter how one feels. A professional has its own responsibility to its customer. But as a team to provide something to society, each need to be tolerant to forgive somebody's weakness. Hard to practice, but this is the way to save a person in depression.
