Based on my opinion, Anna had one of the worst childhoods of all the DP. She starts out BFF with Elsa and that's great! But she quickly unfriended Anna. Anna was always full of hope and wonder until Elsa smashed her dreams. ( I'm not hating on Elsa at all...she is my प्रिय DP) Anna always had her parents until they died. Elsa was NO help whatsoever. I know Elsa was hurting too but she would have felt better if she embraced Anna rather than ignoring her. Anna's sense of Hope is now gone. All of her dreams have been crushed. Yet she still loves Elsa. I don't know about you, but I don't know if I could ever प्यार someone after Anna's childhood. But then again maybe I could. When Anna grew up and she finally became in contact with the outside world, she never knew what प्यार was so she found the first man she saw. Anna for once felt happy with Hans till he left her to die. At that moment there was nothing left. Anna truly belived no one loved her. She thought Elsa hated her and she thought she could never be loved.
