What is the meaning of hurting someones feelings?

well, pretty much, when you get hurt by someone it feels like someone is squeezing your chest, it means you hurt someone really bad, watch what you do.........

It means they have wounded your feelings, hurt your heart, or your pride, or have let you down in some way that makes you unable to feel the same about them as you did before. The sad part is, they people you love, trust , and admire the most, are the people that can hurt you the worst.
