You become afriad to turst people​ .. you become always think of the bad first ,, you become a person who even don't understand him/herself ,, you become able to left anything,anyone​ and go ..you become able to live and have normal days without those who you think that your day won't be without them .. you become more likely to keep what's make you sad in yourself instead of running to friends to talk to them ,,you become more stronger than before 💪
