When Do You Decide When You're Going to Share Something?

When do you decide when you're going to share something? Then? The reason i ask is because for me, again, this is like personal, but for me, i didn't like sharing things. It wasn't until i had a conversation with some one, whether that was a therapist, or whether that was an academic, orWhether that was ike, a friend or a parent or whatever, and i realized, actually having a conversation helps a lot.
