Please help with my step mothers cremation funds

I am her 20 year old step daughter Savannah. My step mother Kimberly unexpectedly passed away the night of November 2nd and was found half an hour after she had stopped breathing on her bedroom floor after a long day of over working herself, she was on 5 different inhalers, and had severe asthma. Due to no oxygen in her brain for 30 minutes she is completely brain dead...  It’s been 10 days, and we still have yet to receive  a “cause of death” from the doctors in the ICU at the Sacred Heart. They have done several MRI’s over the last 10 days to see if they are able to detect any neurological activity throughout her brain and there is none.... They were going to do an apnea test to see if there was any oxygen flow going through her brain as well, but presumed it to be too dangerous as her heart could possibly stop if they did. Our family does not have the funds to pay for her cremation, as this was so unexpected. I am asking anyone and everyone who could possibly help pay for her cremation. After all that she has been through,  she very well deserves it.... She was an amazing mother, wife, step mother, sister in law, friend, etc... she always helped anyone that she could when she was able. If we could do this one last thing, for her, because we love her, it would be an absolute miracle. Please help us.
