“Behold, you desire truth in the inward parts.”
“LORD, who shall abide in your tabernacle?
Who shall dwell in your holy hill?
He who walks uprightly, and works righteousness,
and speaks the truth in his heart.”
The most important person for you to tell the truth to is yourself. You cannot be truthful with others if you are refusing to admit the truth to yourself. All honesty starts with personal integrity.
