Thanks for your very reassuring reply! I appreciate your taking the time, to help ease my concerns. I, also, am a perfectionist and a worrier! I am, also, 79! Additionally, I am a caregiver to my wife! My wife was starting to have a heart attack about 30 years ago, when she was working in the Emergency Room, of a hospital, in Cleveland, Ohio. A wise Doctor tested her, when he saw her becoming symptomatic. They put her in an ambulance and sent her to The Cleveland Clinic Heart Center! The Cleveland Clinic is known for it’s outstanding heart disease expertise! They performed a quintuple bypass operation, that saved her life! She’s had 3 minor heart attacks since, and has had 4 stents put in her arteries, at the regional hospital, where we live now. She’s is in heart failure now! My wife also suffers from metabolic systemic disease, where she has Diabetes, and kidney problems. She can basically care for her basic personal needs, but, being so short of breath, I do most of the other chores etc. So, there are several reasons for my anxiety! Ironically, my dog, a Bichon Friese, was recently disgnosed with diabetes, so we give him 2 shots a day! My wife, also, is a Canadian citizen. She and her parents emigrated legally, to the United States when my wife was a youngster! We cancelled our annual trip to Canada,🇨🇦 to visit relatives, this year, because of the difficulties at the border. We love Canada, and wanted to see her first cousin, especially, this year, because last year, she had lost her business and house, in the horrible Jasper Park forest fire, 🔥 where the whole town was burned to the ground! I believe stress and worry added to my A-fib attacks! Thanks again for your wise advice. It will help me cope better! Take care!
