i'd like some sleep, thanks

I have a problem. I can't seem to sleep in. And then I can't seem to fall asleep. So, I'm essentially burning the candle at both ends. I did everything I could in order to go to bed early tonight. I got up early, got in some exercise and got into bed at 8-ish and had my lights out by 8:30. Unfortunately, at around 9:30, a bit after I had drifted off into my slumber, my phone rings! I knew I should have turned it off. I clicked the person, but it didn't make any difference, all my plans for a good nights rest were ruined. *sigh* So, here I am at 2:30. After tossing and turning for about 5 hours, I decided that I should just get up. :( Can't a girl just get some sleep?
