“Although the idea has been around for ages, most depressed people do not really comprehend it. If you feel depressed, you may think it is because of bad things that have happened to you. You may think you are inferior and destined to be unhappy because you failed in your work or were rejected by someone you loved. You may think your feelings of inadequacy result from some personal defect—you may feel convinced you are not smart enough, successful enough, attractive enough, or talented enough to feel happy and fulfilled. You may think your negative feelings are the result of an unloving or traumatic childhood, or bad genes you inherited, or a chemical or hormonal imbalance of some type. Or you may blame others when you get upset: “It’s these lousy stupid drivers that tick me off when I drive to work! If it weren’t for these jerks, I’d be having a perfect day!” And nearly all depressed people are convinced that they are facing some special, awful truth about themselves and the world and that their terrible feelings are absolutely realistic and inevitable. Certainly all these ideas contain an important gem of truth—bad things do happen, and life beats up on most of us at times. Many people do experience catastrophic losses and confront devastating personal problems. Our genes, hormones, and childhood experiences probably do have an impact on how we think and feel. And other people can be annoying, cruel, or thoughtless. But all these theories about the causes of our bad moods have the tendency to make us victims—because we think the causes result from something beyond our control. After all, there is little we can do to change the way people drive at rush hour, or the way we were treated when we were young, or our genes or body chemistry (save taking a pill). In contrast, you can learn to change the way you think about things, and you can also change your basic values and beliefs. And when you do, you will often experience profound and lasting changes in your mood, outlook, and productivity. That, in a nutshell, is what cognitive therapy is all about. The theory is straightforward”
