It's summer so no school and I get around 12 hours sleep a night but I'm still exhausted and even back in sixth form I would get 12 hours a night on weekends. I do have anemia but I'm on medication for that and I always take the medication when I need to the same with my hypothyroidism which also causes tiredness. So if I take medication and get enough sleep then why am I so tired all the time? Even after I wake up I'm still exhausted.
