The act of lying is not always easy to admit. It may make us feel ashamed, guilty, embarrassed or even angry at ourselves for telling a lie. Sometimes we might even feel like the person who told the lie doesn't trust us. Lying has an impact on the liar as well. When we lie, it can make us feel uneasy or even anxious. It may also cause physical discomfort in our body such as headaches and stomachaches. Lying can have a negative effect on our relationships with others too, especially if we lie to someone we care about.
