The symptoms often made me feel stressed and worried, as I saw them as a sign that something was wrong with my body

It is almost six years since I first detected that something was wrong with my body. My life was stable and generally happy back then; I had a partner, my studies, and a network of good people. For years, I had enjoyed working out and exercising, as it gave me a boost of energy and put me in a good mood, but now suddenly I seemed to get some sort of ‘hangover’ when I’d been exercising; feeling exhausted, getting a slight ‘brain fog’ and generally feeling irritable for up to a week after a training session.
