Amy Norris, 23, from Southampton has postural orthostatic tachycardia syndrome (PoTS) and chronic fatigue syndrome (also known as myalgic encephalomyelitis) (CFS/ME). As part of our, You Don’t Look Sick series about invisible illnesses, Amy chatted to Metro.co.uk about living with both conditions and how most people still don’t understand chronic conditions.
