She began having (then-experimental) surgeries to correct it at the age of two. She had many such surgeries and spent countless days, weeks, sometimes even months in hospital. The number of times she might have died are too numerous to mention.
She never complained. She amazed everyone with her will to live.
In addition to the surgeries and hospital stays, she took all kinds of prescription drugs and faced multiple challenges throughout her childhood and early adolescence: attention deficits, learning issues, and limits on what she could and could not do.
She never complained. She made the most of life.
