Perspective moment

Eric and I have worked together for a long time, and he's become very good friends with his coworkers. One of his friends found out that his wife has cancer again. She's been fighting it for several years now and has been through chemo twice. Eric said that she can't go through it again. I'm not sure if it's because of her history or if the insurance is just saying no. She's going to die. I feel so awful. She and I don't really know each other more than Eric's girlfriend and Mark's wife, but I really hurt for her. I want to do something but don't know what. I'm very open to suggestions. Make a gift? Send over dinner? My problems are so miniscule in comparison.
