i feel i'm very educated about being vegan and about health in general (making sure i'm taking care of myself, getting everything i need, etc.) but i've noticed lately that i just look sort of run down and i don't think i'm sick or anything. my skin seems sallow and while i've always been one to have dark circles under the eyes, they seem worse to me lately and i know i'm sleeping enough (geesh, maybe too much recently!). i'm really hoping this isn't part of aging....especially since i am only 27. thoughts?
