Sleep disorder

It is just the strangest thing. Every now and then when I am very stressed I wake up convinced that my alarm has gone off. Now, this would not be at all tramatic were I getting up at say six or six thirty. However, I get up at two or three in the morning. What makes this so tramatic for me is the fact that I take a twenty minute shower, eat a full breakfast, brush my teeth, and proceed to head out the door. Upon reaching the door, I look at the time and realize that I have made a serious miscalculation. Who gets up at three a.m. when they don't have to? Meth addicts, thats who. I am not a meth addict, so why am I so confused? I need answers, I need sleep, I need to be put in a massive crib and have my mom wake me up at the end of nap time.
