Please help my mama with stage 3 breast cancer

Hi, I'm Nellie. In November my mother, Esmeralda was diagnosed with invasive breast cancer. It started off as a Stage 0 in 2018 and she had a double mastectomy, but somehow, cancer cells were left behind which went into her lymph nodes. During surgery in December of 2023 (a few months ago) to remove the lump and lymph nodes, the blue dye to mark the lymph nodes failed and the mechanism to help the doctor find the lump failed. The tissue that was removed did not contain all of the cancerous tissue. She is now on Chemotherapy, been hospitalized due to infection, and will undergo radiation after Chemo. To stay out of the hospital, she need to take injections that are not covered by insurance to boost her white blood cells. My mama is running out of sick pay and our bills are getting way behind. She is weak, sick and scared of not being able to pay for her medication. As you can see from the pictures, my mom has two children. We are both in college. We come home every weekend and do what we can to help her out. It's always been us since my brother and I were 1 and 2 years old. My father passed away in 2016 from Liver Cirrhosis. Unfortunately, he never maintained a relationship with us and never supported us. It's been a struggle in every way that life can throw at a small struggling family. To go through the whole story would be a novel. We cannot do this alone anymore and I really need any help to keep up with my mom's medication, treatments and bills. I want her to get better and be able to continue to be around for many years. Anything you can do to help us, will be put to the best use. My mom means the world and so much more to me and my brother, I cannot afford to see her leave this world. YOU ARE OUR LAST HOPE to get up to speed and continue fighting.
