I can't sleep

"What is going on?" the question kept repeating inside my head.

I am unable to sleep these days. I do not know why. I felt hungry during the night too. It was like having insomnia. I just want to jump and run around. Something inside me is bubbling up Iand I can't stop it. It is not that I don't want to sleep. Is that I could not sleep. The worst case of jet lag. Why? This is terrible. I going to have breakfast with my parents tomorrow morning. I felt tired, but could not sleep.
Dang. Why? I lead a normal life, I went shopping, hiking, visiting and a lot of stuffs since I came back. Hiahh. That's for now. Hope it is going to be better soon.
