Help For Kinley's Medical ER Surgery

Recently our 9 year old daughter Kinley has had to have Emergency Surgery for a ruptured Appendix. We have no medical insurance and we were denied any financial aid as they only look at our income before taxes etc. are taken out. We have 3 other children we are supporting as well and this amount for her surgery hit us hard we can not afford to pay what the Hospital wants monthly and now feel like we are in over our heads with medical debt. Kinley has struggled most her life with illness or other conditions, she was born with a heart murmur and all her heart valves were crooked with holes and blood pumping incorrect, then she developed random seizures which randomly went away 6 months later, then was diagnosed with a Tricuspid Valve Regurgitation in her heart and also severe ADHD and now this ruptured Appendix. We would be so grateful for any help we can get at all.
