Sleepless

Another sleepless night.  Physically feel extremely tired, but mentally awake. It's suffering to me.
When I was lying on bed and closed my eyes, wondering why I just couldn't get into sleep. Trying few ways to hypnosis myself such like the oldway sheep counting, plays the soft music or have cup of milk. However these all couldn't help. :X
The feeling is like so so so torturing. I want back home because insomnia never will happens when I'm home :/
