Sleep Deprived

It's 6:36 am and I'm still unable to fall asleep. I've been having this insomnia for a week now. I can hardly sleep at night although I'm tired. Yesterday was the same. I did not take a nap in the evening, went for swimming and did about 10 laps and still unable to sleep at night. What have I done? Maybe I should apologize to those that I've sinned of hurt. Please forgive me so that I could sleep peacefully at night.

P.s. I have class at 9am this morning. Hope I can stay awake in class :(
