The lack of familiarity of the situation may cause a person to feel apprehensive and anxious about communicating.

Conflict can create communication anxiety, especially when it is unexpected.

This can limit your ability to communicate clearly and effectively.

Low self-esteem is a common cause of communication anxiety. if you have a low self-esteem, it can affect almost every area of your life. Your self-esteem is how you perceive yourself and how you think others perceive you.
Practice your speech: Practice alone, in the mirror, in the corner, with a friendly audience and record your practices.
