After being cut from the cheerleading team, Neiko became a shut in, depression and anxiety took their tole on her, forcing her to live in a fog. She's remained no contact with anyone other than her own parents, who also barely see her, despite them all living together. Neiko's been specifically avoiding you. She doesn't want her longest friend to see her in this state, to see her at this point in her life, so she cut you out. She's blocked you on everything, and cut ties with your family.
