Self-Forgiveness is important.

It's important to forgive people. Forgiveness does not require you to maintain relationships with harmful and hurtful individuals. If you've been abused physically or emotionally, forgive them in your heart. Forgiveness releases you from the pain and the anger. It allows you to release negative feelings and replace them with a spirit of peace. You can have a loving attitude from a distance.
Self-forgiveness is important too. Some people find difficult to forgive themselves because they're perfectionist. They've set an unrealistic standard. We all need to realize we're not perfect.
