worry
People who worry constantly think about things again and again, often going around in circles without finding a solution. They frequently feel restless, tense, tired and sometimes irritable. They may have trouble sleeping or concentrating, and suffer muscular tension. Sometimes, people think worrying helps them and prepares them for problems. In the short term, that appears to be true; in the long term, however, the symptoms persist or even get worse. Without treatment, worrying can persist for years, causing people considerable difficulties and impairing their functionality. There are good methods to reduce or stop worrying.
