A novel set in a future where the society lived in a closed maybe underground community where they were all telepathic. Punishment was to be cut off from other people’s thoughts. The main character was a teenage girl who rebelled against her controlled society and was punished as above but eventually escaped or was expelled. Outside was a wasteland but people did live there and there was hope and they were free. I remember reading a number of different books by the same author, who was a woman I think. Most of them were science fiction but one was historical set in a Native American tribe.
Could it be The Dream Catcher by Monica Hughes? It's a sequel to Devil on My Back. "Ruth is a misfit. Within the protective Dome of Ark Three, she alone disrupts the Web, the perfect pattern formed by the psychic joining of minds. Other images fill Ruth's dreams, images of a red-haired girl from the far eastern mountains. Could it be that other Arks exist? Ruth must face a hazardous journey as she becomes involved in a dangerous rescue operation..".

Climb the Wind may be the Native American book you're thinking of.
