Please help me with funds for surgery

Hello everyone, my name is Lola and I am 19 years of age. I’ve been on foster care since I was 7 years old and still currently in it. I’ve obtained a lot of medical problem from my biological mom who passed away which included OCD lesions in my joints for which I had surgery for 3 times, ovarian tumor, kidney stones- and now I have something alarming in both my kidneys. I’m supposed to be receiving my surgery to find out what’s wrong. My foster mom is amazing but isn’t really financially comfortable due to covid-19, we receive payment from my foster company but we don’t receive much, I have Medicaid but now something has changed and I need co-payment for the surgery, I’ve been making some deliveries and trying to find work but it is hard, I hate to ask but anything anyone provides- I’m very grateful. If you must see my papers I will post some pictures up, my surgery is called “cystoscopy, pyelogram, right retrograde, ureteroscopy, and a biopsy. This is being taken place at mount Sinai hospital, peds. Again I would be so grateful, thank you very much.
