Everyone feels anxious under stress from time to time. Situations such as meeting tight deadlines, important social obligations, or even driving in heavy traffic, often bring anxious feelings. Such mild anxiety may actually help make you more alert and focused when facing threatening or challenging circumstances. On the other hand, anxiety disorders cause severe distress over a period of time and disrupt the lives of individuals suffering from them. The frequency and intensity of anxiety involved in these disorders is often debilitating, but fortunately, with proper and effective treatment, they can be managed.
