@mark430 You are welcome. Knowledge is power and can help you overcome anxiety, but it can also make you worry thinking that you must have what you are reading about online. There are times you just have to do your best and trust your gut. I learned about overcoming anxiety because I was very fearful and needed spine surgery. On my surgery day, I was completely calm and interested in what was happening around me when I was wheeled into the operating room. I have a background in biology that helps me understand medical literature that I read and I have a great physical therapist who helps release all those physically tense areas in my body. When you are anxious, you start bracing and tense muscles. that can trigger muscle spasms. I've had them in my chest and it can feel like a heart attack, but it wasn't one. I've had ribs that twist because of a muscle spasm. I have learned from my physical therapist how to release the muscles and fascia. I did go to the cardiologist for testing, and went to the emergency room too over this. You don't really want a cardiologist to find a problem, and it's great news when you get an all clear from them about your heart. As for plaque deposits in blood vessels, that starts because of inflammation that is inside the wall of the vessel first, and later plaque is deposited there. Eating a diet to reduce body wide inflammation is good prevention for a lot of diseases. You can also have elevated blood calcium levels if there is a problem with the parathyroid glands. My mom had that, and had surgery to remove one of the parathyroids that caused the trouble, and her calcium levels returned to normal.

I would encourage you to ask yourself questions about the source of your anxiety. I've done that and learned a lot about myself. Finding the source of the anxiety is finding the event or events from your past or your childhood where you formed ideas about how to cope with fear. I was still thinking like a 6 year old and it just didn't serve me well as an adult. I came to understand the fear and accept it, and comfort that vulnerable part of me. To do this and overcome fear is totally life changing. You might ask yourself why you think chelation is necessary to prevent heart disease or if you believe that there is calcification in your arteries and why. There are lots of other lifestyle choices and diet that go a long way in preventing heart disease. I started by writing down a list a fearful events from my life and why I felt the way I did. that showed me a pattern that was common to all of them. I had a lot of anxiety that came from an accident I had where I broke my front teeth as a kid. That in turned caused many dental interventions that were difficult for me, and restorations that failed and had to be redone. So now, I've had some anxiety because in spite of being a good dental patient to try to fix my mistakes I made as a kid, I might loose one of the teeth anyway. Sometimes you try your best, and it doesn't work. I realized I had to forgive myself for my mistake all those years ago and I found some unconscious beliefs connected to that old trauma that was causing anxiety and it made sense, so I could let it go. I think I'll be fine now, and I'll find out in a few days what my future holds. Here is my Mayo story:
