If things are as bad as she claims they are and she's really reaching out for help, there's very little chance that your internet forum is the only place where you'll find the information. I'd be doing some digging and let the results speak for me. As Slartibartfast suggested, I'd then stick to the facts.
"PantsonFire, you said that the house that burned down was in Springfield, right? I was trying to find more information on the community fund you mentioned that your church set up for you and your family. Unfortunately, I couldn't even locate the Church of the Cosmic Muffin in your city. I know that some churches don't have Web sites, so I checked the yellow pages as well. There was no listing. Here are the posts that I was looking at for my information [insert quotes here], did I miss something somewhere?"
or if she claims some sort of malady
"I was really interested in learning more about your banshee anvil kidney, as I'd never heard of the condition. It's apparently really rare. In fact, according to the CDC, there haven't been any reports of it in this country in over ten years. I thought that perhaps the CDC hadn't been updated, but your state's health department also says that there haven't been any cases. If your doctor hasn't reported this to the proper authorities, she could lose her license to practice medicine. You should really be pushing her to report this to the proper authorities. The State Health Department or the CDC likely has more experience dealing with BAK and would have a better idea of how to treat it."
