My experience with death follows.
(Disclaimer: This is not intended to persuade or dissuade anyone from any decision. Do what is best or needed for your own life. I support you. These are just my experiences with the different categories of loss.)
Loss from a natural cause:
(my best friend - cancer)
I damned the God(s) and skies and universe for taking her. I hated the world for the pain and suffering she had to endure at such a young age. She had to be strong for her parents, family, and friends. It was tragic. I miss her a lot and view her as brave, incredibly strong, etc.
Ultimately, we all healed from this, aside from seeing the world as a darker place and missing her.
Loss from suicide:
(my best friend, no suicide letters)
... Everyone close to her blamed themselves. Many attempted suicide after, started self harming or drugs/alcohol, and her family definitely felt the impact. Her brothers cut out the family entirely and disconnected. The mom cannot work or do anything. The dad posts every year about his daughter he misses so much and how much she loved everyone. Nobody really treated her right when she was here, myself included honestly. I will never forgive myself and I will always blame myself as her best friend. Still see her as incredibly strong and brave. I had taken her to therapists as she confided in me with her wanting to ctb. We talked extensively about the subject.
Ultimately everyone is severely damaged except those few that were most mean to her... Those bullies came to the funeral and laughed - not kidding.
Loss from old age:
(Practically my mom/guardian)
I knew it would come. I held her hand and kissed her goodbye before she passed. She was strong and brave, saying she will go soon and she's ready. It brought the family together. We celebrated her life in her last few months of hospice and we all made time for her no matter what. We all felt strong and brave before, during, and after her passing. I felt a peace with the world with it. She was a great women, and just like the others, strong and brave.
Ultimately, it was peaceful and not damaging in anyway, I think.
Much love.
