If it gets to the point that it can ‘ruin a day’ you might want to discuss it with your doctor. However, sometimes just listening to music, taking a bath and letting yourself worry for an hour and getting on about your day can help. I’ve had panic attacks for about ten years. Anxiety is fine, it can’t hurt, and unless the thing you’re worrying about is going to occur in the next thirty days, relax. You have time to make a game plan.
