Am I getting sick!?

I literally did nothing today. I went to school and had english and then swedish and then I came home and slept for a few hours. I woke up for dinner and watched a movie. Was going to go visit Caitlin but I just felt exhausted so I didn't. Now I think I am going to go to sleep again for the night. Just a chill day. I am wondering why I am so tired? Could I be getting sick again? I hope not! Anyway, this was just a day, a really boring day.
