Take a look. Go ahead...take another look at the bully who disrupts your life, shreds any self-worth you have and enjoys putting you through torment. It's certainly not easy as there's no friendly feelings between a bully and their victim.
But I challenge you, the victim, to look into your persecutors life. They have hurt you for their benefit. It's a clear fact that hurting people hurt others. So what issues could your abuser be dealing with to treat you so badly? Is their home life discouraging or unpleasant? Does your persecutor thrive on attention they're hoping to receive from loved ones and not getting it? I'm not defending your abuser's actions. But if you, the victim, can understand why the bully mistreats you, it will be easier for you to forgive. Forgiveness is a benefit for you. When people mistreat you, it says nothing about you but a lot about them.
Please also remember, dear victim, that your value doesn't decrease based on someone's inability to see your worth. Don't ever give someone else permission to devalue you. If you don't respect yourself, don't expect others to either.
Closing thought: You can tell a lot about a person by what they choose to see in you.
