Please help my family give my niece her final wish

Hello, my name is Tracy. I am trying to raise money to cremate my niece and help her 10 year old and 5 year old. She has been in the hospital since the beginning of April fighting for her life. She was doing great and now she is losing the battle. We have to decide in a couple of hours to keep her on life support in a vegetative state or let her go. I think anyone with these options would probably pick what her parents are thinking of doing today. She has no life insurance and my brother and ex sister in law have there own financial issues. I am taking care of her older son who has autism and other health issues. I am the only one who can give money to lay her to rest but I now have a extra responsibility of her son. I'm begging for help and everyone who knows me knows I never ask for help but my niece is only 37 and deserves more then what the hospital gave her and deserves to have her wish of being cremated. Anything will help please. I will truly appreciate it. Thank you
