Momma bunny

My poor Momma bunny has been battling a jaw abscess since April, and it just seems to be getting worse. Tues evening it burst open out of her jaw, and I had to clean it out at my home, alone. Wed we headed to the vet and got yet another little mini surgery to get as much out as we could. And her teeth have overgrown now, as she isn't using them as much. So we had to trim her teeth too.
Today her eye is swollen and oozing. There's a good chance that the upper teeth have overgrown and are now causing an abscess under her eye. I don't know what else to do. I have put so much into this, and there's just no end in sight.
After losing Cookie last month, I just don't know that I can handle losing another. And yet, if this really is another abscess, there isn't much I can afford to do.

I am so overwhelmed I don't know what to do!
