Can't remember my password so can't name change 
A few years ago I was seriously sexually assaulted, which still affects me in certain situations. I am close friends with a couple, one of the couple knows my history and told the other. This person then told another person, who has now told at least three other people. I work with them all.
AIBU to be cheesed off? There is no need for anyone else to know, while there is a genuine reason for the first person to know. It's resulted in me really struggling with knowing who to trust (on daft day to day things, not hugely confidential stuff) when I already have massive issues with learning to trust people.
