I think when someone you know and care for passes, you are in a state of disbelief anyway. It's part of your brain rejecting the reality of the pain.
When a stranger passes, you can be detached from it. Maybe feel empathy at a cerebral but not emotional level, then you go about your day.
The emotional level comes when you have in some way touched each others lives (and that can be online too).
I do often feel like an alien species in my day to day. Realistically I probably at the very least have at least one colleague with ideation, because I have many colleagues. But it's not like it's a topic of general conversation. It's a hidden thing, a shameful secret, taboo.
Here, it isn't taboo. Like is the wrong word, but I can't think of a better one - so I "like" it here, because although I hate the thought of you all suffering - because I know similar pain - at least here I'm not an alien species. I can speak my truth. I can't do that anywhere else.
