Thank all you guys for your help. I finally manage to sleep around 12a.m, waking up (with the alarm clock,of course) at 5a.m and taking a 2-hour nap during the day. It's a combination of regular physical exercises, a very tight sleeping-waking schedule I've followed for the last 21 days.
One reason why it is difficult for me to sleep was not relaxing my mind. I always wonder whether I will not be able to sleep while trying to sleep. I forced to put myself in the state of thinking nothing but I can no longer remain in that state and quickly return the negative thoughts. My mind did go around that cycle until it was too tired.
Actually, even now I don't know how I can overcome it. I just feel it's natural to fall asleep at night...
