Anxiety disorders come in numerous forms, but they all involve extreme sensations of terror that are out of proportion to the situation. Generalized anxiety disorder, social anxiety, obsessive-compulsive disorder, panic disorder, phobias, and post-traumatic stress disorder (PTSD) are the most frequent types of anxiety-related mental illness. While these illnesses frequently coexist, they can also exist separately.
Excessive worrying, mood swings, painful muscles, exhaustion, insomnia, difficulty concentrating, panic episodes, and restlessness are all signs and symptoms of a generalized anxiety disorder.
