I am living proof you can suffer heart issues after major loss. Hence the term: broken heart. Within a few months time I lost both parents and a sibling, 3 funerals in a short period, lost a beloved 15 year old pet, a best friend and at the peak of my business, had to walk away because I could barely catch my breath. Ended up in ER four times due to heart palpitations. Turns out my broken heart and grief overwhelmed my nervous system. I went on small dosage heart RX and sought counsel from a wise 85 yr old therapist to process the 5 stages of grief. I’m doing great now. Thank you for this very important topic.
