Need Immediate Help With Cat That Has Tumor/Growth!!!!

If any pros are here, please help me out!

I'm going to start from the beginning. A month or so ago my cat started to develop what we thought were allergies. She would sneeze and then after a while she started to have discharge from her nose, which caused her to have noisy breathing. At some point after this she developed this swollen tissue of some sort in one of her nostrils. It slowly grew bigger and bigger, until it was clear that it was totally blocking her breathing on one side of her nose and snot was coming out of the other side. At one point her nose started bleeding consistently for a few days on the side that didn't have the growth. We had taken her to the vet and they started treating it as a upper respiratory infection (they also said she had a fever), but told us it was a major possibility that it could be a tumor of some sort. The vet told us to give her antibiotics (Clavamox to be exact) for 10 days and Little Noses (drops that you're supposed to put in the nose for congestion, for babies). At the time we got the stuff from the vet we also got Flax oil and Licorice root (the sticks and put them over water to make tea). A week later we also bought Blessed Thistle liquid extract.

First week we started treatment with herbs she was given the following daily (this was all happening at the same time we were giving her antibiotics): one teaspoon of Flax oil (but she spit a lot out), 1 teaspoon and a half of the licorice root tea (she spit about half of it out).

Second week (daily): The same amount of Flax oil, 2 teaspoons of the Licorice tea (she still spits some out of both) and half a dropper of Blessed Thistle (she spit about half of that out).

Third week (daily): 2 teaspoons Flax oil, 3 to 4 teaspoons of Licorice root tea, half a dropper of Blessed Thistle. During this time she hasn't been spitting out as much as before.

I read about Flax oil, Licorice root and Blessed Thistle working as a cure for someone's cat that has a nasal tumor on a herbal website. I read about how all of the above are good for fighting cancer and inflammation so this is why I started treating her with the above. Despite reading such positive things, the lump in her nose has gotten bigger, bigger and bigger. It was a really big lump and stayed the same for about 2 weeks, but within this week the lump has literally grown within a few days time, creating major facial distortion and today her eye on that side of her face with the tumor/growth is almost completely covered. When the lump started growing within the last few days the snot came back to the other side of her nose too. I don't understand what I did wrong. Why is it getting worse all of a sudden?? All vets I know of here in Atlanta only take animals if you have money upfront or you can use the Care Credit and we've been denied in the past (bad credit). We don't have upfront money for a biopsy and surgery.

There are a few things I look back on that I think could have effected how well the herbs worked: the fact that she was given medication at the same time, that we fed her food and water at the same time we gave her the herbs, I recently read alcohol in liquid extracts aren't good for cats or that the Blessed Thistle was too potent and in too high of a dosage.

What can I do now to save my cat? I read when original symptoms worsen it can sometimes mean that the treatment is working and about to get better. Could this be the case as well? I definitely hope so.

If it's important to know, when she was a young cat (we've had her since she was a kitten for about 6 years now) she used to have diarrea come out of her with no control over it. It would literally just drip out wherever she went and sometimes it had blood. It went away though and she's been great ever since, except the past two years she's had some anti-social problems, which is weird since she has always been so lovable. Within the past 3 months she finally started becoming social with us again, so it's really unfortunate this had to happen.

Also, during this sickness we've been feeding her about a jar of baby food a day and 6 to 7 dropper (it's a thick dropper) fulls of water a day.

Please help! I don't know where else to turn to and I CANNOT have anything happen to my cat!
