girlfriend told her best friend about my secrets?

It happened to me, the first time i trusted someone, was my first relationship, and she betrayed me.
I told her my deepest secrets about myself and my family life no one ever knew besides me... and about 2 weeks after telling her i found on her phone how she told her best friend abozt wgat i told her.

Appearantly she wanted to get another opinion on it to understand me even better


But i am incredbly hurt about it... she told something so intimate other people, now i dont know what to do...
I feel betrayed, some people told me i am overreacting and that i should be glad she didn't cheated on me, but i would prefer being cheated on rather then letting my secrets be know by outsiders...

I am fucking hurt now and dont know what to do... she apologized many times but i feel so betrayed
Help...
