The best way, I think is to combined the suggestions of Sooner28 and Guesser. My son received a head injury in a near fatal accident. He had brain surgery. A lot of people were praying for him. He survived the surgery and the first night. Earlier that day, the doctors were not optimistic.
After surgery there was therapy. It was a big help. He has some issues to deal with but his survival is a miracle.
Sooner28 makes one other excellent point, people who are mentally ill should not be ostracized. People with any physical or mental impairment should be treated with respect. I had my share of grief as a child because of a speech impediment. Kids were tough, but almost every adult thought he was a speech therapist and were always doing an exaggerated pronouncing of the word and then tell me to try it, but talk slower. It did not work. I got some decent therapy in college. Still have some problems, but science, kindness and prayer has always worked for me.
