Re: I'm always tired why could this be?
I agree.. check out your thyroid and get your blood checked as well. Hopefully the doctor can figure it out from there. I'm also a very tired person and wasn't anemic, but turns out that low blood sugar runs in the family. I was eating a low sugar diet and trying to eat VERY clean, but I added back in some extra sweets and feel a LOT better. I'm still tired, but it's often because my blood sugar dips so easily. I just have to eat little things often.
If it isn't anything the doctor can find, then could it be stress or depression? Either of these can cause you to be tired all the time even with plenty of sleep. Some people also really need a full 8 hours of sleep. Even with 7, they may feel very tired. Also, a schedule that varies can cause tiredness, so it's recommended to go to bed and wake up at the same time every day (although I don't see how this could be realistic).
