Hi Chihuahua14,
I think it all start how much we spend our time reading Gods word and praying.
You mentioned how you experiance inner conflict, the more you start investing your time believing Gods love and his promise the less you feel and hear those negative thoughts and view of your self.
For a start post bible verse on Gods love and forgiveness where you see it everyday and internalise it everytime you read it. And suround yourself with people that encourage you to be close to God in bible teaching and prayers. The more you do these things the more your self perspective will change to the image that the bible says about you.
1 John 3:1 See what great love the Father has lavished on us, that we should be called children of God! And that is what we are! The reason the world does not know us is that it did not know him.
Jeremiah 31:3 The LORD appeared to us in the past, saying: “I have loved you with an everlasting love; I have drawn you with unfailing kindness.
Ephisians 2:8 For it is by grace you have been saved, through faith—and this is not from yourselves, it is the gift of God
Blessings
