Symptoms vary depending on the type of anxiety disorder, but general symptoms include:
Feelings of panic, fear, and uneasiness
Uncontrollable, obsessive thoughts
Repeated thoughts or flashbacks of traumatic experiences
Ritualistic behaviors, such as repeated hand washing
Cold or sweaty hands and/or feet
Shortness of breath
An inability to be still and calm
Numbness or tingling in the hands or feet
Panic disorder : People with this condition have feelings of terror that strike suddenly and repeatedly with no warning. Other symptoms of a panic attack include sweating, chest pain, palpitations (irregular heartbeats), and a feeling of choking, which may make the person feel like he or she is having a heart attack or "going crazy."
Obsessive-compulsive disorder (OCD) : People with OCD are plagued by constant thoughts or fears that cause them to perform certain rituals or routines. The disturbing thoughts are called obsessions, and the rituals are called compulsions. An example is a person with an unreasonable fear of germs who constantly washes his or her hands.
Post-traumatic stress disorder (PTSD) : PTSD is a condition that can develop following a traumatic and/or terrifying event, such as a sexual or physical assault, the unexpected death of a loved one, or a natural disaster. People with PTSD often have lasting and frightening thoughts and memories of the event and tend to be emotionally numb.
Social anxiety disorder : Also called social phobia, social anxiety disorder involves overwhelming worry and self-consciousness about everyday social situations. The worry often centers on a fear of being judged by others, or behaving in a way that might cause embarrassment or lead to ridicule.
Specific phobias : A specific phobia is an intense fear of a specific object or situation, such as snakes, heights, or flying. The level of fear is usually inappropriate to the situation and may cause the person to avoid common, everyday situations.
Generalized anxiety disorder : This disorder involves excessive, unrealistic worry and tension, even if there is little or nothing to provoke the anxiety.
