Please read...i really need advice...AND COMFORT..=(?

There are many unexplainable things that go wrong everyday. There are mild heart attacks that can be fooling and the person not think its to severe. My family members have had them as well. I'm 19 and i read this question hoping to provide some comfort, i hope he makes it through this. Be sure and pray for him as much as you can. That's about all there is to do. But God works in mysterious ways. Keep that in mind. I will pray for him as well.
