What Are You Fasting for?

So, today is fast Sunday, and I have a friend in the hospital being tested to see what medications she might need to help her with her autism, and the other disorders she has. She has been in the hospital for a few weeks now, and the doctors still don't know what medications she needs. I just want to ask a little favor of you, could you pray for my friend Audrey? And also for the doctors so that they might be able to figure out what she needs to help her.
