So I've been experiencing extreme fatigue lately. School stresses me out a lot and I do stay up late many nights and get up early. However, Friday's-Monday's I do get a decent amount of sleep but still feel tired. I think I might have an iron deficient but I'm not sure, and I don't know if I should see a doctor or not though, and my mom is not crazy about seeing a doctor about this since she thinks I'm just tired from not sleeping. Should I be concerned or should I just wait till I get to the summer with more sleep?
