No Mood

Don't have mood to start my revision. Why? Get annoyed coz of small matter again. Why am I the one that always cause so much problems? Why do I think so negatively all the time? Why do I always feel insecure? Why must I be unhappy of all these things? U said u wouldn't care anymore if this happen again, and now u really did it. All these are distracting me from starting my revision. I am really not in good mood now. Perhaps I should stop dealing with all these for a month to focus on my studies.
