Maybe

    Maybe these words are right.
    I am not open person.
    So many people are not understanding me such as not understanding them by myself.
    I don't like open my heart .
    I don't like talking to someone .
    I don't like share my sadness to my friend.
    Therefore I am not happy in my life.
     Change my character ?
     I think it is too difficult to me.
     ButI want to be a separate person .
