how much longer does my cat have?

she was diagnosed with Feline Leukemia but may only be a carrier. She originally had an ear infection but seeing as the FeLV is acting as an immuno difeincy disease, her blod count is high, her fever keeps rising and falling and as of yesterday her breathing has become quicker and more shallow...

Additional Details

My cat is very sick. She has stopped eating, she will allow me to "force feed" her without throwing it up. I was able to bring her home last night and the vet filled her with fluids to keep her hydrated. Yesterday her breathing became a bit quick and somewhat shallow. The vet said she can't give me a good prognosis. Im still hopeful but I am so sad. She said their may be fluid in her chest or a tumor but won't know without a ultrasound. So, they gave her more anitibiodics and a steroid and sent her home with me again.

I need to know how long? I took her outside to the grass and she layed there for bit but then got up, walked slowly over to it, ate some of the grass, walked back to me, nudged me and then we layed together. I just don't know if she is leaving me or if we can beat this... help.
