I'm always tired these days and because it's a holiday I've had more of an excuse to oversleep. The problem is for the past week I've had probably 14-16 hours of sleep a night but I'm still exhausted and aching all over. Part of the reason I don't want to get up in the morning is because it's kind of as if I can run away from my problems if I'm asleep. Though I'm so tired and my head and neck hurt constantly. I also woke up with a migraine yesterday morning which was the sorest I've ever had. I'm not talking any medications and my routine hasn't drastically changed. Nor am I up late at night. What could it be and how do I fix this?
