After reading this, I find many connections between what is described in the article and what gifted children may experience in the classroom, including no adult to help them. These kids may be made to feel guilty for being ahead of others, and/or be shamed for not being ahead of all students at all times in all areas. Additionally they may often be called on to be "the helpers" for other children in the classroom (although no one helps them).
Some may say that is possible for a child with no other rejection/abuse/trauma/attachment issues to develop issues just from the experience of being neglected in the classroom.
