Fatigue
Becoming tired and fatigued easily can also be a possible sign of an anxiety disorder. This symptom could be surprising to many people because anxiety is often related to arousal or hyperactivity. For some, this condition might be chronic or follow anxiety attacks. It is still unclear whether fatigue is caused by hormonal changes of anxiety or by other signs of anxiety such as muscle tension or insomnia. Nevertheless, it is essential to know that it could also indicate depression or other conditions, so do not diagnose anxiety just based on this sign. [3]
