What are common signs of anxiety you should not ignore?

Anxiety can manifest in both physical and mental ways that are easy to dismiss but worth taking seriously. Physically, watch for persistent chest tightness, shortness of breath, frequent headaches, stomach problems, muscle tension, and fatigue that doesn't improve with rest. These symptoms often get mistaken for other conditions. Mentally and behaviorally, pay attention to constant worry you can't control, difficulty concentrating, irritability, avoiding situations or people, trouble sleeping, and feeling a sense of dread without a clear cause. If anxiety is interfering with your work, relationships, or daily functioning, or if you're using alcohol or other substances to cope, those are strong signals to seek professional help rather than waiting for things to improve on their own.
