But I ask you, those of you who are with us all day, not to stress yourselves out because of us. When you do this, it feels as if you're denying any value at all that our lives may have--and that saps the spirit we need to soldier on. The hardest ordeal for us is the idea that we are causing grief for other people. We can put up with our own hardships okay, but the thought that our lives are the source of other people's unhappiness, that's plain unbearable.
