If you have been lied to and especially by someone close to you then you were probably wounded. It is usually not something that heals overnight.
People are going to let you down. People might shred you to pieces. They might claw your eyes out and then try to pretend it never happened.
When you have been there, that is where the sweet TRUTH couldn’t taste or sound better. Do you have 7 minutes for some sweet truth? Just 7 minutes.
