Why do I feel anxious all the time even when nothing is wrong?

I’ve been feeling anxious almost all the time, even when there’s no clear reason or problem in my life. It feels like my mind is always on edge, and I keep expecting something bad to happen, even when everything seems normal.

Sometimes I notice physical symptoms like a fast heartbeat, restlessness, or difficulty focusing, but I can’t identify what exactly is causing this anxiety. It’s starting to affect my daily routine, sleep, and overall peace of mind.

Is this normal, or could it be a sign of something deeper like chronic anxiety or stress? What are some practical ways to understand and manage this constant anxious feeling in daily life?
