After the New Year's party

So I went to my parent's new years party and of course had a blast. Friends were there, we chilled out, had some kickass home made food and had a blast. Normally everyday of break I've been staying up well into 3 in the morning and waking up at like 9 or 10 and being just fine. However, I've never felt so off and sleepy today, I swear half my brain is just asleep and i went to bed at 1. Ugh just can't wait for this day to be over...
