Holding onto a grudge can have some really negative side effects. It can destroy relationships by letting anger take place in a disruptive way. Studies have also shown that holding a grudge has negative effects on our bodies. Those that hold onto a grudge may have higher blood pressure and faster heart rates. When we let bitterness seep into one area of our life, it allows it to seep into others. We can become depressed and isolated by holding onto that grudge, so learn to forgive and keep moving forward.
Live, learn, and move on.
