Cover final expenses for the loss of my Father.

My father unexpectedly passed away Sunday morning January 29th 2023. Unknown to us he's lost his battle with cancer. Unfortunately he decided not to tell any of us within the family that he was sick, and kept it all to himself. He died in a very lonely and in my opinion sad way. It's hard to come to terms with why he chose to not have family with him when things took a turn for the worse. And because of those decisions we are unprepared to help cover his final expenses. We're not sure if there are any accounts or insurance to gain access to, to help financially. Any and all help will be greatly appreciated.
