It’s the weekend so why can’t I sleep in?!

I kept tossing and turning and I can’t sleep. I work up feeling a little sick but I’m okay now. I went to bed at 1:30am but I work up at 6:45am and I can’t go back to sleep! Ugh! What the hell?! It’s the weekend. I am not supposed to get up early, unless I have things to do. It’s after 8 and I can’t go back to sleep! Why?!
