Webb, Meckstroth, and Tolan, Guiding the Gifted Child, 192-3
There are three different kinds of depression that gifted children are likely to experience. One comes from their desire to live up to standards of morality, responsibility and achievement that they may have set impossibly high…
Another type of depression may come from feeling alienated, cut off from other people. They may feel that others accept them not as persons, but only as brains, computers or achievers. These children may begin to relate to people only in superficial ways, revealing only what they think others expect from them, only what others are likely to accept, sensing all along their own hypocrisy.
A third type, “existential depression,” stems from their intense concerns about the basic problems of human existence. They are more likely to worry about whether human values are no more than situational, whether they are arbitrary and unreal. Underneath such abstract concerns as whether life has any absolute meaning there is usually the personal worry about the meaning of the child’s own life.
These three types of depression are similar — all have underlying feelings of anger.
