Remember that these people likely didn't do this because of themselves but they also are hurt, likely tricked by the Devil, you don't HAVE to forgive, but its always better for you, Jesus say you must forgive because its better for us, because God has forgiven us, I cant imagine how hard it was to go through that though.
God I believe will do his best to take this pain away from you, and one day, he will make your life such as that you will not remember it. I don't know how quick it will take you to forgive, but forgiveness is a long process so don't feel bad. Good days will come soon BlueRose
