Debbie, I always like to try more natural means of dealing with health issues rather than prescription meds with all their negative side effects. There are foods that are known for lowering blood pressure, there's a listing of some
here.
On the list is Beet/beetroot juice, just drinking one full cup a day is known to lower blood pressure. If you don't like beets, a health food store will have supplements that can be used, SuperBeets is a popular but expensive product that has a lot of good reviews regarding the lowering of blood pressure. I would start the beetroot juice today.
Exercise naturally lowers blood pressure also, simple walking a couple of miles a day in a peaceful area like a park or a forest will help bring it down. Walking or riding a bicycle are the best ways if you're up to it. Do you have any physical limitations where you can't do these things? Do you live by a fitness center where you can use an excercise bike or treadmill? Giving yourself some 'me' time by getting a relaxing massage, working out at a gym, will help you feel better physically and mentally. It also ultimately helps with sleep at night.
Try to relax when you're alone also with deep controlled breathing. Take a slow deep breath through your nose, then slowly exhale blowing it out through your mouth. Think peaceful thoughts when doing it. The mind is very powerful and has a great effect on our physical health, we can guide it to the positive with a little nudging.
I don't know if you're a dog or cat person, but they are known to help the owners lower their blood pressure just by petting them, caring for them, walking them, etc. The dog or cat should have a mellow calm disposition and be very affectionate, so you'd have to spend some time with it before deciding it's the right one for you. Of course if you really don't like pets, or plan to move in the near future, then maybe a pet wouldn't be a good idea.
As far as relaxing, you can use different herbs like Valerian, Chamomile, etc. Chamomile is a very common tea to drink in the late evening to unwind. Magnesium citrate will help relax your muscles too, an Epsom salt bath before bed is good when you can swing it. Some nights I'll take just one half of a Unisom sleep aid. It's over the counter and works very well, it's basically an antihistamine. If I take a whole one though, I feel hung over the next morning. Of course with any supplements, please research side effects or drug interactions.
It sounds like your experiences with the doctor is just adding to your stress and anxiety, unless you need medical attention for a condition, I'd try and just let that go for now and take control on my own. Good luck, thinking of you.
