save my support kitten

Hi, my name is Chalie and that kitten on the photo is my 5 month old baby named Aang. She used to be such a vibrant and playful kitten that would cry if she wasnt getting attention and now she won’t eat or drink anything and has no energy to move around. 3 days ago we took her to an emergency vet where they told us that she most likely has lymphoma and has 3-6 months to live. Today they called us to say that now they arent sure wether she has cancer or not and instead it may be a viral infection. They are going to take a biopsy of her lymphnodes so they can be sure and prescribe her antibiotics because without them she will die . Unfortunately vet bills are very expensive and ive already had to put $1200 on after pay for the vet 3 days ago and the visit is likely going to be as much if not more. I have been diagnosed with autism and im currently on a disability pension so i dont know how im going to get enough money together for these bills. So i have decided to ask for help. Please if you have even a fee dollars to spare I would be forever grateful. Aang is my support animal and I need to do everything i can to save her.
