My friend has been in hospital for two weeks with Covid. I messaged her sister a couple of days ago to ask how friend was and didn't get a response. Later on, a mutual friend of ours phoned me to explain that friend had died but not many people had been told yet, hence why I didn't know. Presumably her sister asked her to break the news.
Needless to say I'm devastated, and guilty because I sent that stupid message to her grieving sister asking how she was.
