Feeling uneasy, restless, or tense are common anxiety indications and symptoms. Feelings of imminent danger, terror, or catastrophe. Having a faster heart rate than normal. Feeling hot or cold depending on the situation. These are all signs of anxiety. Anxious feelings can be mild or severe. If you're feeling mildly anxious, you might have thoughts like "Something bad will happen." Or you could have physical symptoms like a fast heartbeat, sweating, nausea, or diarrhea. Anxiety disorders cause these feelings to be too intense for too long. They can also lead you to make decisions that are not in your best interest (like drinking alcohol excessively or using drugs). The good news is that most people who suffer from anxiety learn how to control it. Cognitive-behavioral therapy is the most effective treatment for anxiety disorders. It teaches you how to recognize and change thinking patterns and behavioral responses that contribute to anxiety. In addition, medication can help relieve anxiety symptoms. There are several types of medications used to treat anxiety disorders, such as selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), benzodiazepines, and alpha-2 adrenergic receptors agonists (clonidine).
