Complexity

There's one thing that bothers me frequently. I think I am an optimistic person, but when I am sleepless, I would become pessimistic. If I sleep well, go to bed early, or take a snap when I feel tired, everything would be perfect and wonderful to me. I live in the dorm with my roommates now. We live in different ways; of course, everybody has his/her uniqueness. I do agree with that. However, I can't really stand it when they ignore or neglect my need. They often speak or play the music loud freely when I am sleeping. I don't like this way people wake me up. I try to calm down whenever this thing happens. I hate myself that I dare not express my feelings directly to other people.
