You are not alone — It’s just that people often don’t like to admit it, but holding grudges is common for people to respond to their feelings when they’ve been wronged.
During my workshops with students, I ask them to write their grudges on paper. Once they finish writing all their grudges, I ask them to put them in the fire and see it burning. The spark lit on their face is unmissable.
Try it yourself whenever you feel angry, bitter, sad, mad, worried, or exhausted. It works!!!
