Help Jennifer Butler with medical bills

Hi, I’m Chris McDaniels. My sister Jennifer developed severe neurological problems after COVID that left her unable to walk for many months, caused her to have multiple seizures per day and unable to perform many cognitive tasks. She has lots of medical bills and has been unable to work. She’s had more than $10,000 in out of pocket medical costs over the last few months and just recently discovered due to an administrative error, she has an additional $3000 in overdue medical costs.
