19. You feel bitterness and resentment
Holding grudges is bad for your health. Having been through a tragedy or trauma, it’s natural to harbor some bitterness about what happened. It could be a divorce, the death of a loved one or losing your job.
An unexpected event even may leave the person feeling cheated by what happened. This can make the person feel a great deal of bitterness.

Bitterness leads to resentment. The person may feel like a specific person or event is what caused their problem. They begin to resent the person or people involved in what has happened to them. Their resentment seethes under the surface and begins to consume them. Soon, there’s nothing left except for a burning desire for some revenge.
Studies suggest that not dealing with bitterness can lead to illness in the long-term. Feeling bitter and resentful exhausts not only the body, it affects the mind and soul.
