Understanding generalized anxiety
It's common to feel anxious from time to time, especially if your life is stressful. However, severe, ongoing anxiety that interferes with day-to-day activities may be a sign of generalized anxiety disorder (GAD). It's possible to develop GAD as a child or as an adult. Living with GAD can be a long-term challenge. In many cases, it occurs along with other anxiety or mood disorders.
Symptoms
Generalized anxiety disorder symptoms can vary. They can include:
Constant worrying or obsession about small or large concerns
Restlessness and feeling keyed up or on edge
Fatigue
Difficulty concentrating or your mind "going blank"
Irritability
Muscle tension or muscle aches
Trembling, feeling twitchy or being easily startled
Trouble sleeping
Sweating, nausea or diarrhea
Shortness of breath or rapid heartbeat
There may be times when your worries don't overwhelm you, but you still feel anxious even when there's no apparent reason. For example, you may feel intense worry about your safety or that of your loved ones, or you may have a general sense that something bad is about to happen.
In most cases, generalized anxiety disorder improves with medications or psychological counseling (psychotherapy). Making lifestyle changes, learning coping skills and using relaxation techniques can also help.
