There is book called "the four agreements" written by Don Miguel Ruiz. It basically gives you four guidelines to live by in order to live a happier life. The agreements are simple and profound but extremely hard to put into practice. One of the agreements is "Don't take anything personally" Here is an explanation from the book description:
Don't Take Anything Personally: Nothing others do is because of you. What others say and do is a projection of their own reality, their own dream. When you are immune to the opinions and actions of others, you won't be the victim of needless suffering.
In other words people who feel good about themselves don't run around hurting others. Usually those who hurt others are looking for ways to project their pain onto others.
Don't know how useful this would be to you, but keeping this in mind does help out a bit:
THe other three agreements include:
Be Impeccable With Your Word: Speak with integrity. Say only what you mean. Avoid using the word to speak against yourself or to gossip about others. Use the power of your word in the direction of truth and love.
Don't Make Assumptions: Find the courage to ask questions and to express what you really want. Communicate with others as clearly as you can to avoid misunderstandings, sadness, and drama. With just this one agreement, you can completely transform your life.
Always Do Your Best: Your best is going to change from moment to moment; it will be different when you are healthy as opposed to sick. Under any circumstance, simply do your best, and you will avoid self-judgment, self-abuse, and regret.
