I got up very early! It really means that I slept for few hours and got up to initiate a day at 4 o'clock in the morning. Yesterday, I wrote that I might be insomnia. It may be not wrong. An improvement I achieve from the last night to this morning was that I was able to go to bed before 1 am.
I still have to work on my sleep pattern. It might cause my work and private life harmed. I still can't accept that I was suffered from such a thing in spite that I used to be good at sleeping anywhere and anytime. Anyway, I have to face it and solve it as soon as possible.
