"It is your own perspective and values that break your heart at the sight of your [disabled, chronically ill] child. Are you really doing her any favors? If you, her father, never smile at her and always have tears in your eyes, always sad on her behalf, how can this be healthy for her? She's doing her best, yet you are causing yourself misery and harming your child.
"In fact, even if she compares herself to her healthy friends and feels down about being sick, you should be the one encouraging her, saying 'Health is not the be-all in life and bodies are immensely diverse. You are beautiful just as you are.' If you say this half-heartedly while crying inside, you will not even convince yourself, much less your child.
"You have to change your thinking. Your grief comes not from your child but from yourself. You are weeping at your own reflection. Parents of disabled children should be happy, and if they are not, it is because their desires were not met. This also makes children think of themselves as less when they deserve respect just as they are, not to feel themselves to be lacking for not meeting an arbitrary standard."
