Just a thought

I am feeling like a fool. Whenever someone I care for is not doing that well in the emotional department, I end up opening my big mouth about medicine. Why? Who knows, I am really concerned for my friends, but don't really know how to fully be there. What good can I do? I tend to try to replace their sadness with humor, but it doesn't always work. Can't God just cure their sadness? Yes, but then what would they have learned? How do I know? What good would it do for God to cure everything and heal us all? We would never need Him, and a life without Him would really suck.
