URGENT! Please help save Lollipop

My cat, Lollipop, is suffering from Autoimmune Hemolytic Anemia. I put a link, but basically it's a disease where her body is attacking and destroying her own red blood cells. This morning she was found under the Christmas tree meowing constantly in pain and distress. As my family and I tried to slide her out while she was on the tree skirt she looked very lifeless and couldn't get up. Every time we tried to move her slightly she would cry out in more pain. I noticed that she had a very hard time breathing, so we rushed her to an emergency pet hospital.

After the blood work was done the vet told us that she has Autoimmune Hemolytic Anemia, but she hasn't found the exact cause. The urine wasn't able to be tested, because Lollipop happened to urinate on the blanket we brought her in. We're hoping that when they're able to test her urine that they'll be able to find out exactly what caused this and if they're able to fully treat her. When we left the animal hospital she was in an oxygen chamber. Lollipop is in very critical condition at the moment and she's going to have a blood transfusion and be put on immunosuppressive steroids to help her body stop attacking her own blood cells. Even with all this we don't know if she'll make it. I'm hoping she improves, but the vet did mention that the first blood transfusion might not take and she might need more done. We don't have the money to spend on countless blood transfusions since it's $500-$600 each time, so I'm asking for help. Any donations will be going towards the initial medical cost which is estimated around $1,814-$2475 is just for treatment and housing until Monday. After that we have to go to another vet and it's seeming very likely that we will have to do more blood transfusions and other treatment, so any additional donations will go to that as well. It really pains me to see her like this especially since it happened so suddenly. Yesterday morning she was just fine, so I really don't understand what happened to her. Any help is deeply appreciated. Thank you.

Final Update:

I'm very sorry for not posting sooner, but I really just couldn't handle doing it yesterday. Even now it's very hard. Yesterday (12/15/2015) at 7:10pm we had to let go of Lollipop... We were crying all day yesterday when we found out in the morning that the doctor found 2 masses near her heart and he said it look like it had spread. She had fluid develop in her chest and abdomen. He had put her on medication for the fluid in her abdomen the night before, but it wasn't doing much of anything and it had spread to her chest area. When we went to go visit her she had deteriorated from the day before and her breathing had worsened. The doctor said that she couldn't be treated and she was in the later stages of the cancer and anything we would be doing we would just be buying more time, which she had very little of. Before we went to go visit we had planned to let her come home for a day or half a day one last time before letting her go... but we couldn't do that. We weren't prepared to see her like that... and we didn't want to bring her home just to watch her suffer and deteriorate even further, so we decided to let her go then. None of us were ready to let go... we really thought we had at least one more day with her... It's really hard to type this. We were so happy to see her improve... and then to get that type of news... it was just really unbelievable. I'm glad she's not suffering anymore, but this is so hard since it was so sudden. We all miss her so much... things will just not be the same anymore. The house feels so empty without her. We love her so much. She was so silly and cute and she loved all of us. Not a day is gonna go by without us missing her. We love you Lolli, we always will.

I really wanna thank everyone for their support once again. You were very kind to try to help us give her a chance, but we just didn't know that she was so bad off. We'll never forget what you tried to do for her. All of the donations went towards the medical bills. Thank you again from the bottom of our hearts.
