Dear Sad Sister,
I am so sorry for your brother and for you that this challenge is here for you now.
I wish there were a way of undoing this injury. It's not fair at all. I hope that your prayers for his recovery will be answered.
Who knows yet how bad the possible disfigurement might be. Here, too, you have awful prospects for the near term. On the other hand, a loving heart will help you adjust, as fearful as you may feel now. No question, this is a heavy burden.
I agree with Soapy Bubbles--there is so little one can say to be of use at such a sad time, and obviously nothing we can do of a practical nature, even. But the thoughts and prayers I can add to those already sent your way, along with the other help you will find, may yet be useful to you.
At the risk of saying the obvious, I'll remind you that in this stressful period it is even more important to take care of yourself. Grief and worry can make people slow and careless too, and you need to be attending to your own health if you want to be of help to your brother. And as always, the ability to model hope and pleasure in living is an important gift that we offer the survivors in our lives--by way of invitation and encouragement to rejoin the dance.
My heart goes out to you both.
I'm just a poor wayfaring stranger, a million miles away from home.
