Overcoming a Stuggle

When I think of overcoming a struggle, I think of the book Nineteen minutes. A girl refuses to donate bone marrow to her dieing sister, because her sister secretly asked her too. She gets a lawsuit against her parents so they can't make her donate it. Plus, the only reason she was born was so that she could donate to her sister and try to save her life. But her sister just ends up wanting to die anyways. She overcame her struggle by going for going for what her sister truely wanted not what her parents told her to do.
