Why Me??

I don't understand everyone in this world can change too .... but why I'm the one who change .... I try to change ... ;'( my mum always said I love to complain ....I change that ..... and my friend say that I never tell the trurt .... and change i try to say thing straight .... but then they said I'm too straight !! I'm dizzy with all this thing ...... I need to control myself not to complain my brother....sister....and etc. but then I'm angry sometimes of my brother reaction .....
so I scold him .... then my mother say he love ppl to smooth talk to him not that mad .... so i change again ...I try not to scold .... but I don't know if there is any use .... I wish I'm a prefect girl .... but I'm not ....I can't do anything only ... nothing.... I guess..... I think I should take a deep breath and relax once a while ~~ it's better like this ....
