No one knows our bodies or our subjective experiences like we do. This means we can rest secure in our knowledge of ourselves and what we’re going through, even when the medical profession doesn’t understand or believe us. Migraine is a weird and changing disease. It affects all of us differently, and every attack is a little different than the one before. This means that no one can understand your life, symptoms, or illness like you can. This can be incredibly empowering: you are the expert. But, it also carries great responsibility: to live as happily and as fully as possible, you must listen to your body and trust your instincts.
