Even if your grievances are “justified,” you have constructed an identity for yourself that is much like a prison whose bars are made of thoughts. See what you, or rather your mind, is doing to you. With the awareness comes transformation—and freedom.
If you feel that you have, or sometimes have, a victim identity, feel the emotional attachment that you have to your victim story and become aware of the attachment to think or talk about it.
You don’t have to do anything—just be there as a witness.
