Cheated

What's e feeling when u believed in someone and told tt person a secret tt u wan no one else to noe...but in e end she told someone abt it?Why is it called a secret anyway if u're to spread it around?How does she noe whether tt someone would not leak e info out to others?I feel so cheated!!!She's making me feel tt there's no one i can believe in tis world and i cannot tell anyone my secrets in e future anymore.I keep it a secret bcos i noe tt e consequences when others noe abt it maybe sth tt i cannot handle...so y muz she make things so hard for me now?I'm so worried and frustrated now!I think i wun believe her ever again.
