We all have a person in mind that is highly opinionated or judges others harshly. This may even be a characteristic you recognise in yourself. If we're personally dealing with low self-esteem, judging other people or criticise them harshly is often a sign a deeper issue that we have with our own insecurities. If we're feeling low about ourselves, it can feel good disparaging other people.
How CBT helps: CBT can help build our self-esteem by first of all enabling us to identify our negative thoughts and behaviour. Your therapist will work with you to discover some of the limiting beliefs you may have of yourself or your abilities and help you develop, new and rational beliefs about yourself. If you find yourself harshly judging the people around you, your CBT therapist will work with you to identify the source of these negative feelings and replace these with positive helpful thinking patterns that will eventually contribute to an improved view of yourself and the world around you.
