My brothers Cremation Bill I owe

My brother had no Ins. or any money he lived on poverty level.  It was left up to us 3 sisters to come up with the 1500.00 and I am disabled and live poverty level too with a roommate.  So, I desperately need the help to get my 500 pd in due time and I truly can't afford to make the pmts on this.  Thank You'all
