So very touched by your post, and extending my condolences for your loss.
Having witnessed extreme depression up close, and knowing my point of reference is narrow, I too find it sickening to read comments that are glib and rather idiotic.
It was explained to me this way; for a person suffering RW did, it is akin to never being able to get clear reception on a radio. It’s all static and the brain never gets a rest.
Found that analogy helpful in understanding the tortured pain they may be dealing with, daily.
I trust our friend Socrates as neither glib nor idiotic. What will you say, it’s OK? No, you let them know it is wrong. Clearly wrong.
