Often your enemies on the earth plane can be your friends from the realms of spiritual world who have come to help you to learn lessons.
Instead of hating these people, love them, because they give you the greatest opportunity to grow and be free of your karma.
So many souls have hate in their hearts because people have hurt them or upset them. Often that hate will never be dealt with and will be taken incarnation after incarnation until in one incarnation it will manifest as illness.
Every soul, who comes into your life, comes to teach you something. The person may be your mother or father, family member, or someone close, but no matter what they did, they did it to help you. Instead of feeling hate, turn that hate into love, thank the person for being there to help you.
Often the person who becomes your enemy, the person you come to hate or despise is your best friend in the spiritual realms, chosen by you to help you to grow, they have agreed to be a part of your life to do this.
When you can let go of your hate for all those who have hurt you, and replace this with thanks and love for the opportunities they have given you to grow and learn, then you become such a great soul.
Let go of your anger, hatred, bad feelings, be thankful that someone cared enough to help you. That in itself is true friendship.
