I understand how you feel about getting upset that people disclose such personal information without your okay. Sadly, almost everyone that I've told or knows about my transition felt it was okay to let other people know without my permission, some think I don't know that they have spoken up. Yes, it hurts, but it's almost unavoidable. Personally, I try to live and let live rather than bring it up as i have very little acceptance in my life, but I wouldn't lie by saying it hasn't changed how I saw people and whether I felt I could ever trust them again or talk to them about personal stuff. I wish people would realize how much it hurts when someone shares something so private without permission. Again, sorry you had to deal with it. As for how you handle it, that's something only you can decide. In either case, I hope things work out for the best for you.
