I feel you, although don't exactly know how well my health is (haven't been to the doctor in like 3 years) I feel like my entire body is slowly deteriorating. I started having night sweats, heart palpitations, dizzy spells suddenly within the last year. I had a scare a few weeks ago that I was going to have a heart attack because I started having intense pressure in my chest and was convinced I was gonna die. On top of that I have a genetic condition that hasn't affected me yet, but I fear it might worsen one day and I become disabled or worse. I think because of outside forces when facing death we become scared of the concept more than when we have control over our fate, sorry for rambling but haven't seen anyone talk about this lol
