Forgiveness is never easy when the injustice is strong and the hurt deep. So, please know that you are not alone. There are several approaches you can take. First, you might want to start by forgiving someone else who is easier to forgive as a way to build your confidence. Also, are you expecting to be done with the forgiveness process in a short amount of time? If the hurt is deep it can take months of steady effort to forgive. Finally, I urge you to look toward the fruit of your forgiveness: lower anger, more hope. As you see these as endpoints to your forgiveness it might strengthen your will to persevere.
