I feel old...

Sigh. Sometimes I wish I were a kid again, without the responsibility of having a job, bringing home food, and travelling on my own to school.
Maybe I feel this way due to this constant lethargic feeling I've been having.
I proved something today. I slept at 5 am, and I still woke up at 11 am. But even when I sleep early, like at 10 pm, I can never wake up earlier!
My internal clock is messed up. Maybe another reason why I feel old.
Sigh. Sometimes, I wish I could wake up one day, and not have to worry about what has to be done that day.
