When someone has deeply hurt you, it can be extremely difficult to let go of your anger. But forgiveness is possible—and it can be surprisingly 16 to your physical and 17 health.
“People who always forgive others 18 less depression, anger and stress and more hopefulness,” says Frederic Luskin, Ph.D., the 19 of Forgive for Good. “So it can help 20 on the wear and tear on our organs, reduce the wearing out of the immune（免疫的） system and 21 people to feel more vital.”
So how do you start the forgiveness? Try 22 these steps:
Calm yourself. To defuse your 23 , try a simple stress-management technique. “Take a couple of breaths and think of 24 that gives you pleasure: a 25 scene in nature, someone you love,” Luskin says.
Don’t 26 an apology. “Many times the person who hurt you has no 27 of apologizing,” Luskin says. “They may have wanted to hurt you or they just don’t see things the same 28 . So if you wait for people to apologize you could be waiting a(n) 29 long time.” Keep in mind that forgiveness does not necessarily mean 30 to the person who upsets you.
Take the control away from your offender. Mentally replaying（重播） your 31 gives power to the person who caused you pain. “ 32 focusing on your hurt feelings, learn to look for the love, beauty and kindness 33 you,” Luskin says.
Try to see things from the other person’s view. If you empathize（把感情移入） with that person, you may 34 that he or she was acting out of ignorance, fear—even love.
Recognize the benefits of forgiveness. Research has shown that people who always forgive others will get more energy, better 35 and better sleep.
Don’t forget to forgive yourself.“For some people, forgiving themselves is the biggest challenge,” Luskin says. But it can rob you of your self-confidence if you don’t do it.”
