As per the press release, she 'died of sadness' from her husband's death. I thought that's a euphemism for suicide but turns out it is a real medical thing. Grief so strong that it weakens the heart muscles, and you literally die from a broken heart.
It is just infinitely sad and I cannot imagine the pain she must have gone through. But I cannot help but see a glimmer of beauty in such a passing. Love can persevere so strong that it stays with you until you die. May she rest in peace. May she be united with her husband.
