Oh no, I’m so sorry to hear this!
Fidget’s retirement account loan is a great idea, or if you have any home equity you can usually get a loan against that. You may even be able to get a loan against a car title (not 100% sure about this one though). I would hate to suggest selling any collectibles or valuables, but just throwing that out as an option too...
Hang in there! Wishing you luck!!
