What you should do, is asking your doctor for a 24 hour blood pressure
monitoring, which will give a more correct picture of your
blood pressure and how it changes when you are anxious, calm, asleep, etc.
The focus on how important normal blood pressure is, and how dangerous high blood pressure is, can make anyone anxious and produce false blood pressure results. And 149/80 is just mildly elevated. Anxiety will make the blood pressure increase in everyone. It's a normal response.
