Help my sister fight to survive

About a little over six months ago my sister began to not be able to eat and when she did it would just come back up again. She went to dr. after dr. with no answers as to why. She started loosing alot of weight eventually turning into not being able to drink anything either including water. She has gone weeks without eating or drinking anything and without trying to as well. She has gone from 121 lbs to 81 lbs. They have recently put her on a picc line to do hydration therapy to try to get her to gain weight and help her try to eat and hold it down. She has been in the hospital 5 times alone this year. They cannot run anymore test until she is able to gain some weight and hold something down. She has lost so much energy she can barely get out of bed on occassions and is not able to work at the moment. We are financially struggling with bills and medical bills trying to get her healthy again I am reaching out and asking for help any little amount would be greatly appreciated so that away she is able to take time off from work and focus on getting better and not be stressed out about worrying about how she is going to afford bills.
