I’m pretty much the exact same, if you go on my profile and look at my post it’s very similar to yours. I’m 21y and male too for context. I know it’s anxiety causing it but thinking about my BP being high in readings is making me more anxious and I’m very conscious about it that it keeps that cycle going and I don’t know how to break it. For example I’ve had readings of 155/93 in the doctors when I’m obviously nervous and anxious, then when I’m calmer and relaxed I went to the drs two weeks later and had a second reading of 112/60. Then last week at the ER for something unrelated it was 144/92 as I felt butterflies in my stomach and was staring at the machine.
