Yeah, it can be tough to balance it. Sometimes, especially if it's a loved one, just listening and letting them vent and then offering if there's anything you can do to help/support them is all they want. Even if you have something that's directly relevant, it may not be the right time to share. There isn't really a silver bullet guideline to these types of things since it can be very context dependent.

Thank you for saying this. I know a lot of people have a hard time with it, but once you establish trust and connection, you can then share your experiences that are similar with most people. There's some who are very little sense of self security that hearing this will break that trust.
