Saying goodbye to husband and Recovering from Loss

SEE UPDATE!!!!

My name is Kayla, I am raising money for a ceremony for my late husband and to have him cremated. He died suddenly on the 5th of March of a fentanyl poisoning. We were able to make his death mean something by him being an organ donor and being able to save 4 people's lives with his "gifts".

His heart saved a 27 year old female.

His liver saved a 44 year old female via Directed Donation.

His left kidney saved a 66 year old female.

His right kidney went to a 56-year-old male.

Since I am next of kin, I am responsible for all of his medical expenses from before time of death & funeral costs. His mom said she would only cover some if it is done 100% her way, and i had no sah ij the matter. His entire family and I do not get along, and have drug my name through the mud. As if it's not a hard enough time already, right? It was always just him and me against the world.... And as his wife i just want to have the send of he wanted and respect HIS wishes, which his family could care less about. He was the strong one and I'm just trying to see his wishes through to the end.
