Is she on the autism spectrum?

What you describe is more than the typical challenge I mentioned. Have professionals come up with a diagnosis?

I’m sorry it’s no wonder you are so stressed.

I don’t think what you are describing is NPD it’s too early to diagnose that. There is something else developing and the professionals may not quite know yet.

I watched a talk with the author that wrote a book about Elon Musk. He is a very complex individual with Autism/Aspergers and he experiences some very drastic mood swings that challenge him. He may have bipolar in addition to the Aspergers. He goes days with very little to no sleep.

It sounds like there is no typical and more of a quest of what can work best for whatever challenge your daughter has.
