I have a problem worrying about my blood pressure too. I found that I am more scared when I take it, rather when I am not taking it. My problem is that they found it high a few times, because I get terrified and my heart beats really fast. My therapist proved it to me that I don’t have blood pressure, but sometimes I can’t help it to obsess about it. My advice is (because I know) is to stop taking it and try your best to forget about it. Work it out with your therapist and ask her/him to help you. Good luck!!
