It seems crucial that you realize deeply that your worth and value does not depend on anyone else. You are a person worth being loved and called to give love. Keep saying to yourself: “I am being loved by an unconditional, unlimited love and that love allows me to be a free.
The more you can come to realize this, the more you will be able to forgive those who have hurt you and love them in their brokenness.
Without a deep feeling of self-respect, you cannot forgive and will always feel anger, resentment, and revenge. Loving one another means forgiving one another over and over again.
