AIBU to be unsure how to react on social media when awful events are unfolding?

[LostSight]

Does anyone else feel uncomfortable on, (for example) Facebook about all the messages and comments that are made following appalling events?

I just find it hard to know how to respond. I sometimes find it overwhelming and, perhaps rather trite when so many people who are not remotely involved post messages.

Are there people who have been involved in any major incident? Did you find it positive that there was such a public outpouring of sympathy?

I hope this doesn't come across as insensive. I just never know how to react and it makes me personally rather uncomfortable. Modern life has complications that weren't there when I was young.

I ranted at my DH for marking himself safe, he's not been to London for 4 years! However we only live 50 miles away and he has "friends" in America who had asked if he was safe (apparently there's a button to click for this - because actually sending a personal message is apparently too much!). People like to feel involved...
More infuriated by the people taking photos rather than helping though.

I don't say anything unless there's something specific I want to get across or comment. I asked a friend of mine if her police officer spouse was on shift in London, and he was, in Westminster as well, so I said I'm glad he's safe.

Other than that, I'm not a Londoner, I'm not personally impacted, and I don't know a lot of Londoners, so didn't feel the urge to share any particular messages.

I do think the positive posts are good though because we shouldn't all start frothing at the mouth like right wing nutjobs when this sort of thing happens - it's important to remember that although there was one absolute monster who took people's lives yesterday and ruined many others, there were hundreds more good people at the scene who acted heroically, with kindness and strength, which I find reassuring.

Had this yesterday on a group chat (I am the only one based on London) out of a group of 8.

One person in particular loves to be the voice of doom - she is always the first to post messages about events [she must be so bored she is hooked up to Sky News 24/7] and she seems to revel in it.

Lots of her posting about how she used to work nowhere near Westminster and how her BIL's dog walker was nowhere near Westminster 24 hours before the attack.

The highlight was this nugget though:

her: OMG I am meant to be going to Charing Cross next week
me: I am in central London now and its eerie
her: but you don't work anywhere near Westminster

Seriously the arrogance, self importance and sheer stupidity of what she said may be the final nail for me in that group chat!!!

Thank God I am not on FB as I'd have lost my mind!

Just because you once walked on Westminster Bridge or once went on the London Eye doesn't mean you were involved in yesterdays awful events.
