Recently I've noticed a lot of vague problems with my health, for example losing mental sharpness, weakness, fatigue/no energy, slight depression/anxiety that seem to have gradually grown over about a year or two. My symptoms are similar to hypothyroid symptoms however I'm only 20 so feel this is unlikely. Though a lot of my symptoms are vague, I feel something is wrong because I eat healthy, exercise etc and have always been full of life as a person so really feel not myself
