Imagine being a mother with a 5 year old that has Leukemia. Terrible already.
Now imagine that while treatable, the treatment is a no-go for your religion.
Now you are refusing, and using lawyers and the state regional authorities to essentially argue for your right to refuse what might very well be the only way your child will live further. You probably don't understand much of what is going on. (don't know where the father is because he isn't mentioned).
You are going to court for the right to kill your 5 year old, while not wanting your 5 year old to die.
She may never forgive herself.
