Just because some people treat you badly, it doesn't give you the right to do the same to others. You can break the cycle of negativity & abuse. Instead of feeling angry & hateful, learn positive and empowering behaviour. Focus on your reaction rather than the behaviour of others
Learn to admit your mistakes. Eat humble pie, swallow your pride and know that you will be respected more of it. Many fail to understand this. The earlier you admit that you have done wrong, the more time you have to learn and grow from them. It's a lesson well learned.
