There are some T's that just don't like labels... mine is one of them. Some believe that labeling can lead to that diagnosis becoming a major part of how a person is viewed or how they view themselves. It can more or less become a self fulfilling prophecy. There have been studies where a diagnosis can lead to dehumanization and a lack of individualization.... it becomes more about what the client has and less about who the client is. It used to really bother me that T wouldn't give me a diagnosis but I have embraced that fact now.
