DBT does not ask you to give up your emotions or to feel "the right way" to please anybody else. Emotional invalidation is what caused most of us to need DBT to correct what we learned that hurt us or kept us from developing skills that other people have.

The first part of emotional validation is to observe and describe and understand and accept your emotions. You feel the way that you do for a reason. Emotions are important. They make us who we are, and they communicate what is important to us, and they motivate us to take some action, and they validate us.

Even if you decide to change an emotion, first you need to understand it and validate it. When you change which emotion you are expresing it, the object is not to hide or cover up or reject the original emotion. One technique is to act "opposite to current emotion" such as to smile when you are afraid, or do something nice for someone you are mad at. Even then, the object is not to get rid of the current emotion, but to express a different emotion.
