There's all kinds of suicides, and all kinds of reactions to it (all valid). Suicide happens to all kinds of people for all kinds of reasons. It's not a monolithic subject. But it is really nice to see everyone talking about it.
To suicide, I've lost several family members, several friends, and many acquaintances. I've thought about joining them. Most recently, January, I lost a great friend. The wreckage that he left behind is staggering. I haven't been as upset by a death, ever. The flood of emotions is so strong you can't clearly define what it is you are feeling... loss, anger, sadness, guilt. It's all there, and it's all vaild. It sucks.
There is sometimes an underlying problem (drugs, alcohol, gambling, insecurity, abuse, illness) that we might be able to help with. Or help them find the help they need.
All I can say is, be kind to one another. Be fucking kind like people's lives are on the line.
