BP fluctuation. Well. i have a query!

Hello Hope you are doing well. I have a query regarding my BP. I have an anxiety issue but it's under control now but sometimes it happens if I am angry or i fight with someone. I am taking olmezest 10 mg for my BP as coz of my anxiety my BP fluctuates a lot. Now my question is day time after taking the medicine etc my BP is normal but sometimes in the evening it goes to 141/90 or 150/95. If I go from one room to another and if I check after sometime it comes to 132/82 128/80. Is it normal for BP to fluctuate like this. My breath changes when I start taking BP and I feel anxious that the number might come high. Does this changes the BP reading? Even sometimes I feel woozy and sometimes blurry vision but doctor said that might be due to my spondylitis. I get anxious even thinking about any heart issue or BP. Family history Mom: High BP Dad: Diabetic and heart patient. Recently I have gained weight also but I am into sports and is active. Will be doing basic blood tests soon.
