One time after her divorce and during an ongoing conflict with her daughter, my daughter "causally" mentioned a suicidal ideation. That got my attention, and I kept in close contact with her. She suffered from degenerative discs in her neck, a result of being thrown from a horse when she was a teen. As such, she tended to self-medicate(alcohol) along with prescription pain meds. As a consequence, she had extremely high blood pressure for quite a few years, which ultimately led to a brain bleed, which took her life 3 years ago. I can't help but think that in some way she may have wanted to be shed of physical and emotional pain, and that her death was, for her, a welcome relief.
