Confused

Am I that irritating, am I such a nuisance? Am I that surplus? Why is people giving me the attitude I did not even do anything to them...Why they want to treat me like that? And another thing I finally found out that I have 3 personalities in me...I keep on changing time to time....I cried again I don't know for what...I really don't know...Lots of shit problem happends in this week...Don't feel like sayining anymore...My existence now is only for my parents...
