Need Help To Pay For Surgery

My name is Trena Amezcua. Back in November I was in the hospital where they determined that my gallbladder was bad and had to have surgery to have it removed. During surgery they discovered that my liver was in pretty bad shape and was extremely enlarged. The surgeon couldn't believe that it was even able to fit in me. The surgeon insisted that they only way to get my liver back to normal size was to have the gastric bypass done. I have done everything I've been required to do the past 5 months and even though i have insurance, it does not cover the 287.00 assistant surgeon, the 250.00 for the required meds and protein meal replacements and other bariatric meds, I've also got to pay the 125.00 after care for the next year after surgery. My husband is on disability and we barely survive off his income. I have to have all this money paid before my surgery. My surgeon is thru Roller Weight Loss in Fayetteville, Arkansas. I have been informed that if I do not have this surgery and my liver being in such bad shape, I will end up with cirrhosis and have to be put on a transplant waiting list where I will more than likely die before receiving a new liver. Any help is appreciated. Thank you for your time
UPDATE:
I had my last required doctor's visit today and was informed that I have 3 weeks until pre-op where all funds are due that day. Any kind of help is appreciated. Thank you
