The pattern of Sleepless

I am really strange. Certain days in a month I feel more optimistic and have more energy. Tired but can have little sleep. I am most productive during this period. Certain days (mostly...) I am always drowsy. 8hrs sleep a day is much less than necessary. Even worse is when the depressive feelings come. Fortunately the anxiety has become less powerful than it used to be.

There is nothing bad if one can sleep little in some day and sleep a lot in others. But it gets bad when one takes a routine job like me. I am the kind of person that will follow my natural instinct. Change the habits would be the last thing I wanna do. mmmmmm....... I will be exhausted tomorrow!
