Former EMS, here, Doc.
Yes, the sense of failure and grief are intense, but only until you realize that some things are meant to be.
If you are willing to do your human best, even to the point of what would be described as 'superhuman effort', and yet fail, there just might be a reason.
We don't understand any more than a small part of God's plan, and usually that in retrospect years later. Frankly, we aren't capable of understanding all of it any better than someone who only ever saw a gear tooth move understands a Grandfather Clock.
'Handling it' amounts to trusting that the creator of all is in control, and He knows what He is doing.
Everything happens for a reason, whether we understand it or not.
Funny, how the more learned we are, the tougher that is to accept.
That doesn't mean we shouldn't do all we can to stop injustice, combat the evils of this world, help those in need, comfort those in pain, and heal the sick and injured, it just means that it won't always work--even if we did everything right, and we won't understand why, at least at the moment.
When we have done all we can, it is in God's hands, and trusting Him is the key to sleeping at night.
