A.L.
It does sound like your anxiety rises when you start to worry about your BP. When I was first dx with high BP they had no categories - you just had high BP or you didn't. I remember buying a BP cuff and checking my BP too but then I just got rid of the cuff and moved on as the med controlled the BP and I saw may Dr. many, many times over the 30 years since I was dx. My BP is 99% of the time just fine.
As SC suggested, check this out with your Dr. If your BP and all is OK that will be good news.
Kindly,
