Emotional barriers can be tough to overcome, but are important to put aside to engage in conversations. We are often taught to fear the words coming out of our own mouths, as in the phrase "anything you say can and will be used against you." Overcoming this fear is difficult, but necessary. The trick is to have full confidence in what you are saying and your qualifications in saying it. People often pick up on insecurity. By believing in yourself and what you have to say, you will be able to communicate clearly without becoming overly involved in your emotions.
