Anxiety about bp checking. To do now.

For the past 2 years I have been working from home and have had a sedentary lifestyle. And A few weeks back I was having 140-150/90-100 bp so I took all heart test like ECG, 2d echo, tmt, chest x ray (all were normal) took blood test too(CBC, lipid, lft) all were normal. So the doctor suggested bp monitoring for a few months. And within 1 week of exercise and walking my bp was back to normal 115-135/70-90 and it was in this range from 1 month. But whenever I get stressed or hear anything related to heart disease on news or from anyone i get anxiety then when I take my bp that time it goes to 150/80 and then after five minutes when I get myself relaxed it comes back to 120-130/70-80. How to deal with this plz. Some suggested ambp but whenever I see bp instrument I am getting anxiety which increases my bp so if I took ambp and my anxiety will come as it have to wear device all day. So during that day i will be anxious which may give false high reading due to anxiety. So what to do now.
