If you're alive, you've probably had someone lie about you behind your back, try to assassinate your character, or make you question the things you believe to be true about yourself. We've both been there and had a hard time coping with it until we allowed God to intervene. Dealing with difficult people is a given in this life, but it's up to us to pray and seek God on how to protect our God-given identity and stop allowing ourselves to be victimized by others.
"At one time we too were foolish, disobedient, deceived and enslaved by all kinds of passions and pleasures. We lived in malice and envy, being hated and hating one another. But when the kindness and love of God our Savior appeared, he saved us, not because of righteous things we had done, but because of his mercy. He saved us through the washing of rebirth and renewal by the Holy Spirit, whom he poured out on us generously through Jesus Christ our Savior, so that, having been justified by his grace, we might become heirs having the hope of eternal life. This is a trustworthy saying. And I want you to stress these things, so that those who have trusted in God may be careful to devote themselves to doing what is good. These things are excellent and profitable for everyone." - Titus 3:3-8
