What made me look into Atheism was my own Mother's death. I was her caregiver and she had six months to live. When you have that time to prepare you can ask what the person wants, how they want their affairs handled. My Mom said to scatter her ashes on the mountain overlook. I asked her what kind of service she wanted and she said she didn't believe in Any of that crap. She'd ,"read all of the books and it was All crap (even Buddhism). Don't read any prayers, no priests, nothing." She made me promise. At one point someone plied the Lord's Prayer into my hands saying I'd know what to do when the time is right. I said sure and when they weren't looking I crumpled it up and threw it away.
My Mom said she didn't know what came afterwards and she didn't care. She'd been living with HIV and before that had battled with Schizophrenia. Cancer was just another thing to beat. In any case she'd already come to terms with her mortality.
What Christians don't get is that in the Five Stages of Grief; Denial, Anger, Bargaining, Depression, Acceptance when you have a fairy tale of what comes afterward you never exit Denial or Bargaining. Regardless, you never make it to Acceptance. My Mother accepted the reality of her death. It was still painful, it was still scary, but she accepted it and so did I.
Suffering is expecting something from reality you're never going to get. Liberation lies in Accepting it.
