DD7 has been having some existential blues lately. She'll just feel suddenly alienated from her life and surroundings, to try to describe what she's intimating, and sad. I am watching it, talking with her, and if it ever seems overwhelming I know of an excellent local gifted-focused therapist. But mostly I think it's common for gifted kids and just want her to know she can talk to us about it. I certainly remember feeling the same as a child and being thrown and frightened. So far telling her I relate and it can get easier to handle helps, and holding her, and keeping her busy (new ideas, stimulation, outside play) helps.
