Oh I feel so much for your daughter. I was often the “friend” left out…. And I was also often called “so nice” by peers, teachers, and parents. Though, too many years being left out made me bitter and angry. I’m finally getting to a place of trusting women again, but it taken several years to untangle the hurt of being left out and treated poorly over and over. I hope your daughter finds a better group of true friends who value her presence.
