It is good thing when the one who has caused the hurt can step forward and say, "Hey, sorry that went to far." A big hug usually helps too. True friends will do this, the others well here is what you should do for them.
Pray for those who have wronged or hurt you. That is really all you can do. If you ask you Spirit Guide, for them to find some-sort of peace of mind and heart - you, yourself receive blessings. If you pray for those who have been mean to you or those who treated you like sh-- you shift the negative energy. Seeking revenge and you being mean to them just going to cause negative energy circling you. An eye for an eye and we all go blind! Whether it is a day, week, or ten years the negative energy will show back up in your life.
Let your conscious be guide.
