Rest Ministries is a Christian site that supports those with chronic illness. They have encouraging articles, helpful info, books and products, and a quarterly magazine (I had an article published in it last issue).
But You Don't Look Sick is a website with a wealth of info. They have a lot of articles, products, and support info, and they have a message board I frequent. The boards are a great place to get advice and support from people who know exactly what you are going through.
The founer of BYDLS, Carolyn, also volunteers her time to help people apply for disability, and those she helps have something like an 89% acceptance rate within four months of the first application (as opposed to the national rate that's more like 60% acceptance within a year or two). There's a whole section on the boards dedicated to SSI/SSDI.
On my own website Sparrow's Flight: Fibro I have a page that lists the symptoms of Fibromyalgia and specifically how they affect everyday life. At the bottom of the page I also have a list of suggestions on how people can reach out and help and encourage anyone in their life who is chronically sick or disabled.
