I think she was happy; She has a loving father (hehe), a beautiful, amazing mother. Her life was great. She already had the Cinta of her life, even if she didn't know it then. She was surrounded sejak people who loved her and who didn't think she was a freak. Everybody loved her and thought she was the most amazing thing to ever grace the planet. <3 I think Nessie was happy, mostly... except when Bella wasn't happy, then she was worried.
Happy&Unhappy. She had amazing caring parents and a family who stood up for her anytime and everytime. And people who would defend her. though let's just not neglect the part when,even from Bella's point of view, Reneesme looked frightened and unhappy. She didn't know what was going on,The volturi... Her parents fighting, calling the other vampire families. She really was unhappy,she didn't want her family and Jacob to die because of her.
