Need funds for my Hospital Bill due to malignant tumor

I am Angelina Brandares. I was rushed in the hospital due to hemoglobin count decreasing to 4. With my age of 71yrs old it is critical to have this condition. I am also suffering from tumor on my stomach. I had my operation and the tumor was removed but according to the pathologist, they cannot distinguish what kind of cancer is this. I am already for discharge but my bill went up to 400k ($7000) because of so many test, lab procedures plus medicines and the hospital won't allow us to leave. They want us to settle it in full and they are not accepting promissory note because we are on the payward section. We do not have any choice but to avail the payward section due to no space or room available in the charity because of covid. We even checked other hospitals too.Please I am begging for help to pay the hospital bill. I only have one daughter who is working but her income is not enough to cover my bills and the other one is taking care of me who has no job.. My husband is already a senior and no longer working. I also need to undergo chemo therapy but I have to be discharged to fully recover first. I am begging for help.
