I also get the feeling of a tight rope drawn around my waste or higher up. Seems to come on when I eat more salt than usual. After alittle while, it subsides. Taking time released metropolol, Low dose. If I take more, I have no spirit to do anything, no sex drive, no appetite to exercise. Only live from habit. No way to live. 72 and struggling with myself. Depression also comes and goes. Brother dying of cancer. We had a sad relationship which was mostly no relationship after the age of 9. This finalizing that we will never connect makes me sad. But am grateful that he had a successful life. And so did I though they were very different. Separating the physical heart stuff from the emotional heart stuff just isn't possible in my life. We are a whole person.
