A blog with useful insights and lots of shared stories
This is an American website that was created by two mental health professionals. They talk about all types of grief and signpost to useful resources. While these specifically relate to America, their insights are really well written and they have a large number of people sharing their stories, which we haven't seen at this scale before.
They have a specific page on grieving a suicide death, with insights and commentary from a mental health perspective. At the bottom of the page, you can find comments with people sharing their own stories.
