Why do I always look so tired?

Hello everyone, I'll get to the point quickly. I'm not happy with myself at the moment because my face always looks so pale, and I also have dark circles under my eyes and a generally tired face. I really don't know what could be wrong. I've lost 15 kg and am now at a normal weight. I eat mostly healthy food, i.e. God's food. I avoid processed sugar and try not to buy bread from the supermarket. I bake my own bread, for example, so I mainly eat things that are good for me. I also exercise regularly or do sports at home, dancing, home workouts, etc. I always drink enough water, but for some reason I look so dead. I swear I don't get enough sleep, help me😭 what could be wrong?
