Ferret please help asap?

On sunday night I noticed my ferret had bloody stools she was not moving just laying there not eating nor drinking I could not get ahold of a vet even the emergency ones not one would anwser even drove over there and banged on the door. So I took her in first thing yesterday morning they kept her all day hooked her up to a iv tryed to get blood three times with no sucess they also sedated her and they couldn't get any then. So I brought her home at 5 yesterday about midnight she still was not awake they told, e to rub karo syrup on the gums she woke up so her stools are back to normal but she is falling over when she walks she is drinking and eating a little of gerber baby food chicken in chicken gravy im really worried she is sleeping alot and it is very very hard to wake her also as sunday night I can get ahold of anyone. Any ideas of what might be going on. Sorry its long but I am very very worried about my baby. Thank you
