19 year old Leanna diagnosed with Aplastic Anemia

My baby sister, Leanna, was just diagnosed with apastic anemia. Shes only 19 years old, and shell be needing a bone marrow transplant. She cant work, and her health insurance doesnt cover much (were looking into finding better health insurance for her, but dont know where to start). Her hospital bills will be through the roof if we dont figure something out soon. On top of shes not working so shes scared she wont be able to pay her rent this month, she has 2 cats she loves dearly that still need to be fed while shes in the hospital, and driving back and forth to see her is getting to be expensive. My poor baby sister is in the hospital crying because our mother is also sick and she doesnt want her to have to worry about hospital bills. Shes only 19, this isnt fair, shes scared and lonely since shes only allowed 1 visitor, and our moms too sick to be with her, so the only person she can see is our sister in law, whos struggling going back and forth to take care of Leanna and our mom. Anything anyone could do to help would be greatly appreciated. Even just prayers will be so helpful right now. ❤
