This is the latest post on a blog I follow, written by a woman with a chronic illness, not entirely diagnosed but including Dysautonomia. This post is about the unhelpful responses you hear from friends regarding your chronic illness. I love her ability to articulate her experience, she writes a lot about the emotional side of dealing with chronic illness, very frank and maybe not for the sensitive though (language etc.)
