Anxiety is a very unpleasant feeling. Your heart may race. Your stomach may be in knots. You may have trouble sleeping and trouble concentrating.
Medical doctors see a lot of patients with anxiety. About 20% of patients seeing a primary care doctor actually have a diagnosable anxiety disorder! They may have many different symptoms, but anxiety is the underlying issue for many.
Untreated or longstanding anxiety is certainly not good for your health. It’s a marker of stress, and we all know what long-term stress can do.
