This is an open letter to anyone suffering from a mysterious, chronic illness. Invisible illnesses like chronic fatigue syndrome, fibromyalgia, food sensitivities, multiple chemical sensitivity, anxiety and many others are unfortunately poorly understood, leading to even more suffering and isolation. Through this open letter, I wish to show anyone suffering from these types of illnesses that they’re not alone and that things can improve. But I know how difficult it is to believe that when you're suffering and that's why I really wish to get this message across.
