Headache!

Last night, I tried to sleep earlier than usual time because I want to wake up early. But for some reason, once I am in bed my mind starts to wonder anywhere and only ends up to some bad memories of my life. I don't know exactly what time I fell asleep. All I know is I woke up with headache and no energy. I wish one day my headache and problem will go away. All I want in life is to live happy, content and have peace of mind.
