Helping my mom with hospital expenses

About two months ago, my mom went to the doctors, turns out she has bronchitis. She had medication and was staying home to get better.. especially during the coronavirus pandemic. A few weeks went by and she wasn’t getting better, she’s been to the doctors multiple times after that and all they told her was to go home and rest it out. Things just didn’t seem right, finally we got her to the hospital where they tested her for coronavirus (she’s tested negative) then told her to go home and rest and if it’s hard to breathe, come back next week. Luckily a different doctor took her in and after xrays she had to be rushed to Rochester. They found fluid in her lungs, thinking it could be cancer. She’s only been in the hospital for a week and has already been in surgery 3 different times. They’ve drained the fluid out each time.. it just keeps coming back. After xrays, they found she doesn’t have cancer (thank god) but we’re all very unsure how long she’ll be in there for. Anything would be helpful and appreciated. We’ve had a great support system ❤️
