What Self-Esteem Problem?

Many adverse human situations seem to get or go that way because of something known as low self esteem. As with other poor behavior patterns, it has achieved that status of medical malady. According to one internet source: Low self-esteem meets the criteria for an illness or disease because: Low self-esteem is uncontrollable in nature: People with low self-esteem feel insecure. They are not sure what normal is, and they are not comfortable with themselves or with others. They are experiencing behavior over which they have no control, just as a person with cancer has no control over the cancer. This uncontrollable nature of the behavior makes it an illness; therefore, the behavior is "sick'' behavior. Yeah, right. Here's my challenge, I can't find scripture to support this assertion. Actually, I don't find much in scripture to support the idea that people have a low opinion of themselves at all, even when they should. What say you?
