Help Brooklyn Cat get a tooth extraction

My cat Brooklyn needs a tooth extraction and treatment for an abscess. She is a rescue cat who was so malnourished she couldn’t jump when we first got her. Now she’s eleven years old, and is one of the kindest cats I’ve known. She has an appointment today to get emergency treatment because she’s in pain. Next week she will have her tooth extracted. If anyone can help- any amount is appreciated. I am currently fostering some rescue kittens and between doing TNR and getting the rescues care, I need help with my own cat. I just hate seeing her in pain. She is living with my ex in NYC and neither of us have the funds for her surgery right now . I can post all vet bills here. Thanks to anyone who can help. I know there are so many people and problems that need help these days.
