Please help support shars heart transplant

This is Shar. She is an extremely bright and creative 10-year old. She loves her family, Legos, Gachaverse, Wonder Woman, unicorns, anime, video games, crafting (all kinds) and science. At age 6, she began teaching herself astronomy and anatomy, and wants to be a doctor when she grows up. She has two cats named Clover and Sagwa, who regularly sleep with her at night. She was also diagnosed with heart failure the day after her 10th birthday. In addition, she and her family are homeless, which puts a very dangerous amount of stress on her. Her at-home medicines are not helping her improve and the advanced heart failure team at her hospital have begun the process to approve her for transplant. Currently Shar's parents, both fully disabled, make enough reliable income each month to barely cover the cost of the single hotel room where she lives with them and her older brother and sister. However, that leaves nearly nothing to afford food, transportation, clothing/laundry and other basic necessities. While the hospital has been very generous with some resources, there are many things they cannot provide regularly or at all. As yet, it's unclear how much of the cost of the transplant itself and aftercare that the hospital can defray, so Shar's family is planning for needing to absorb the full cost.
