There's the old saying "when life gives you lemons, make lemonade" that can be true in the world of cancer. One must overcome the obstacles they are faced with. Stand tall and fight back hard. While I myself do not have cancer and have absolutely no idea what it's like to have the cells in my own body go to war with themselves, I can be empathetic to my daughter's struggles.
To help dry her tears.
To be her shoulder to rest on when weary.
To kiss and hug away the "it's not fair"ness of it all.
To give her whatever she wants in spite of the trouble it may cause mom...i.e. farm animals.
Because when life gives you cancer, you get kittens.
Although the world is full of suffering, it is full also of the overcoming of it.
