For some time now I’ve been dealing with trust issues among some members of my family. They want you to open up and talk to them, but they end up telling others about what you thought you were telling them in confidentiality. 
When I talk to someone about things that I am going through, the things that I am sharing contains some sensitive and private information. If I wanted that information shared, I would have shared it myself. So, there’s a reason why I don’t want everyone to know my personal thoughts. 

There is also people who get mad at you for whatever reason and release this information in retaliation. So, I believe it should be kept between a trustworthy person because some things are not meant for everyone’s ears.
