Medical expenses and new car fund

Hi, my name is Jordan, and I’m doing this fundraiser for my sister, Jessica. My 2-year-old niece, Esme, is nonverbal autistic, which comes with struggles of its own. But, the week of Thanksgiving she went into hypovolemic shock and was septic. They couldn’t figure out what from but were able to get her well enough to go home after 4 days. On Black Friday, her husband was driving home from primary children’s hospital to go to work and was hit on the freeway, completely crushing the rear driver side door in and the guy who hit him doesn’t have insurance. So, my sister is left to buy a new car on her own. On December 3, my niece then had a tonic clonic seizure, stopped breathing, and lost her pulse. My sister started CPR on her until the ambulance arrived. She had another seizure later that day but they were unable to determine the cause of these. She continues to have absence, focal, and gelastic seizures. My sister is now left with numerous medical bills and the need for a new vehicle, not to mention all the new specialists and tests my niece continues to need now. My sister works full time as a nurse and has 3 other kids at home that she cares for. She is doing her best to stay afloat right now but things just keep piling up one after another pushing her back down. Any help would be greatly appreciated.
