How to stop being offended?
First of all, you need to reconsider your requirements for the people around you. Just understand that everyone around you has their own idea of what is good and what is bad and it does not always coincide with yours. Give every person the right to not conform to your ideas - it's normal that we are all different.
Do not judge people and remember that you can also make mistakes. Learn to ignore the faults of others while focusing on your own imperfections.
Distance yourself from people who are themselves deeply unhappy, always complain about life and strive to ruin it for everyone and everyone. Such people are best avoided.
Ask for forgiveness for your mistakes if you offended another person. In most cases, this generates a response.
Do not keep negative emotions in yourself - it is better to sort things out once than to spend a lot of your precious time thinking about them.
Remember that resentment destroys relationships in the family, and do not let her do it. Your life is not a series of random events, but something that you build day by day. Therefore, everything is in your hands - to be offended or not, this is only your conscious choice.
