Confess All is an expression that means to reveal everything or to acknowledge all the things that one has done wrong. The antonyms or opposites of this expression could be phrases such as "hide everything," "keep secrets," "deny wrongdoing," "withhold information," or "conceal the truth." These antonyms reflect actions that are inconsistent with confessing all, such as lying, deceiving, or failing to take responsibility for one's actions. Engaging in these actions could result in negative consequences such as loss of trust, damaged relationships, or even legal trouble. Therefore, it's often better to be honest and confess all, rather than trying to cover up the truth.
