One way to answer this question is to continue with the above metaphor, that is, you need to see a psychologist when the container gets too full and strategies aimed at helping don’t work. For example, you may find that talking to a friend or reading a self-help book doesn’t change things for the better. Other indicators that you might want to a see a psychologist include: you know the problem is too big or complex to handle easily; others suggest you need to talk to someone or get help; you’ve tried numerous strategies over the years and have had some success with the issue but no real lasting or deep changes have occurred; or, you just don’t seem to be reaching your full potential in your marriage, career, friendships, or hobbies.
