Yes, I would speak to your therapist.....There is a saying: "You are only as healthy as your biggest secret(s). I may have misquoted some, but that is close. Family members don't want to hear the truth, so if you speak, you will have to live with the consequences. As for "confessing"----you didn't do anything, so you have nothing to confess....words are powerful, so you might consider using the word.....exposing the truth....secret. Then there is "the truth shall make you free."
