John's funeral

John has been fighting liver cancer for over a year now... John has been failing real quick this month, his nurse was here today and her report was to John,myself & Maureen was that his blood pressure is super low & his time is here. John has an appointment next thursday with one of his doctors & the nurse thinks he won't be here for it. John doesn't have a life insurance policy, he wants to be cremated.. We would like to have a mass & a gathering after that mass but we dont have the funds to do that. We'd be very grateful for any help we can get...
