Lili needs surgery

PLease help Lili....
Lili normally loves to snuggle and has the sweetest disposition.  Latley, though, she hasn't wanted to be squeezed or held at all and has been having trouble taking a full breath.  The vet took some x-rays and found that she has a bladder full of stones, too big to pass. Not her gall bladder. Her bladder. She's squatting constantly. She need surgery now. I'm trying to raise the money myself, but my resourses are limited, so it will take a while. The longer I wait, the longer she's in pain. We had diagnostics done on the rest of her system and the vet said that, aside from her stones, she's in perfect health. She's currently on antibiotics and pain medication for an infection she developed from the straining of a constantly full bladder. She won't eat because it causes too much pressure to have a full belly.   I'm trying to make her as comfortable as I can, but she's clearly in a lot of pain. I love her so much. She's my sweet mamas.... Please help her. Anything will be greatly appreciated. Please share her story....Lili and I thank you
