I'm 18 years old and about to graduate high school. I am so tired throughout the entire day and even when I wake up for school in the morning. Some days I get to tired I can barely stay awake in the car when I'm driven home from school. I get 9-10 hours of sleep a night; I usually sleep from 9/10pm to 6:30/7:00am. I have a decent diet but I don't know what to do. I have a history of thyroid issues on my mom's side so I don't know if that might be the cause. Please help!!! (I can't take this anymore)
