So far, research        (show) that people who forgive can have more energy, better appetite and better sleep. “People who forgive show       (little) anger and more hopefulness,” says Dr. Frederic Luskin, who wrote the book Forgive for Good. “So it can help reduce the tiredness out of the immune system and allow people        (feel) more energetic.”
So when someone has hurt you, cool down first. Take a couple of breaths and think of something         gives you pleasure: a beautiful scene in nature, or someone you love. Don’t wait for an        (apologize). “Many times the person who hurt you may never think of apologizing,” says Dr. Luskin. “They may have wanted to hurt you or they just don’t see things in        same way. So if you wait for people to say sorry, you could be waiting a very long time.”
Next keep in mind that forgiveness does not necessarily mean        (accept) the action of the person who upsets you. Instead, learn to look for the love, beauty and kindness around you.

To gain perspective, you may want to write a letter to        (you) from that person’s point of view.
