Medical bill nightmare

Hi my name is Kim I was recently diagnosed with congestive Heart failure and copd along with coronary artery disease! I had no idea I was Ill until I went to the Er for what I thought was appendicitis! My Bp was 250/175 I was told I was at risk for a heart attack and blood clots as soon as my blood work returned. I spent 5 days in the hospital and then needed a heart catheter done.

I have no insurance and the insurance I tried to get won’t pay any of my preexisting conditions ( congestive heart failure copd or my coronary artery disease) for 1 year after diagnosis. I now have $25,000 in medical bills and I still haven’t received my bill for the Heart Catheter. I’m afraid I won’t receive care because of my unpaid bills.

any help would be greatly appreciated!
