Hypertension and anxiety!

I officially have hypertension even though my only symptom is slightly elevated blood pressure. No swelling, urine tests are fine, and labs are fine. So I have weekly ultrasounds and twice weekly NSTs. I get so nervous before my appointments and I just have anxiety now about them because the last 2 times they made me go to the hospital because of blood pressure (it was only 145/70!!).

Anyways, does anyone have any advice on staying calm before appointments? I’m going 2-3 times a week now and I really don’t like being nervous before each one. My husbands deployed so I just worry they’ll send me to the hospital again and I’ll be alone. Please let me know!!
