Afraid of dying

I am freaking out. I get high blood pressure because i have severe anxiety, panic attacks, white coat syndrome, my anxiety is very health related. I don’t have chronic hypertension, none of my doctors are concern, I sometimes get very high readings, my pcp, cardiologist, obgyn, even the mfm doctor ( high risk pregnancy) are not scared for me, i have a mfm doctor because my obgyn suspects a Velamentous cord but it seems to be marginal instead, so i have to get growth scans, all i can think of is dying , i am 29 weeks pregnant, with my second after 13 years, i have a 12 years old daughter, 1 miscarriage and 1 ectopic with surgery after her in 2018 and 2020, now pregnant with rainbow, also get tachycardia constantly. I do therapy once a week, but i really want some encouragement because I don’t want to die young, im so scared men im so sorry🥺🥺🥺🥺
