You are holding a secret, either your own or someone else's, and it is starting to tear you up from the inside. This stifled energy is harmful and needs to be let out. Find someone safe with whom you can discuss this.
You are untrustworthy when it comes to keeping secrets. Try to practice intermittent silence as to discern what should be kept and what should be let go.
