When you or a loved one has mesothelioma, it can seem like there is so much to worry about. That's normal. It is a misconception that all worrying is distressful and unproductive. There are healthy levels of worrying that motivate us to do what we need to be happy, successful and healthy. When worrying becomes overwhelming and feels uncontrollable, then most people experience distress and feel anxious. Obviously, the challenge is to keep our level of worry at a range that motivates us, not give us anxiety.
