sleeping issues

Today I woke up at seven am after sleeping fitfully for the past few hours. I had problems falling asleep last night and things did not improve much throughout the night. After forcing myself back to sleep I remember waking up again at nine o'clock. Time after this point is incomprehensible to me because somehow I ended up in a state of sleep or in a temporary state of unconsciousness/ semiconsciousness. At twelve o'clock i woke up in pain and was extremely uncomfortable. I was still in a groggy state of mind, yet I had this sicking feeling in my stomach like I had forgotten to do something that was really important. At first I was I lie with my head in my pillows, looking up at the ceiling confused. Then, it hit me. It was 12:00! I had just missed two of the three of  my classes I was supposed to have today, & to make matters worse, I was prepared for both of them. I was so angry, flew out of bed, refusing to believe the time, and realized that it was twelve o'clock and there was NOTHING I could do about the classes I had just missed.
I missed Engl. class & Philosophy and today might have been one of the WORST days EVER to miss them. In Engl. I was supposed to have a test on The Kite Runner, & in Philosophy I was supposed to take a quiz and go over the rest of Kaunt's epistemology on law and government.
I am SCREWED.
To make matters worse, we are coming up on break in a week. I didn't work my ass off all this time to miss 4 classes in the past two days! I didn't work this hard to fail my classes and have to RETAKE them.!!!
UGH f%*ck SLEEPING ISSUES!!! =[
