I am tired ALL of the time. I'm a 16 year old female and I'm a bit overweight. I usually go to bed around 10 and wake up at around 7.30. That's like 8 and a half hours of sleep (Isn't 8 hours what you're supposed to get?) I pretty much never have breakfast and then walk about 2 miles to school. You might think this is the problem but I've been doing that for about 3 years now and I've only been feeling this tiredness for about 4 months now.
I'm pretty stressed at school and home so I don't know if that's the problem but, as I said before, I've been stressed at home for about a year, though being stressed at school is pretty recent (about a month). I just want to sleep ALL day. I'm getting behind with school work because I just can't concentrate, sometimes in last lesson I literally almost fall asleep.
Please, What could be the problem? ._.
