One of my very good friends was just diagnosed with cancer. On the week of his wife's last chemo treatment for her cancer. I know life isn't fair, but this is just ridiculous. I know that what I feel is unimportant compared to what they feel, but I feel so powerless and so exhausted. I don't know what to do to help them. I don't want to overwhelm them with my need to be useful. I'm at a loss.
