Help Cover My Heart Surgery Expenses

I had a heart attack and emergency surgery 3 1/2 years ago. I've had 3 heart surgeries since. I had to retire and go on Disability. I've had physical therapy a few times, and now I'm on several medications and see several specialists. I've changed insurance a couple of times, but I've racked up numerous medical bills and expenses that have not been completely covered by insurance. I get by, but I'm not equipped to handle sudden or emergency expenses. I'm just asking for help to recover some of my expenses and to pay off miscellaneous medical expenses and credit card debt I've had to incur. Thanks for any and all help. I'm very thankful and appreciative for life!
