I think watching threads and landings or aborted landings/diversions like this is very reassuring actually, but I know you might not agree!
When I look at all the movements today, those that landed got down safely, obviously due to pilot skill and working to the airline's limit rules for attempts etc. Those that didn't or couldn't land were the result again of pilot decision/airline rules/max wind speed etc. and there were safe diversions.
In past years I would have died of fright if on a plane during something like this. However I now realise that it is all done within the safety limits and as my old Dad used to say, "the pilot doesn't want to die either!" (GermanWings is a different matter and very traumatic and sad though not connected with safety).
I don't like being involved in a windy landing, or a go around, or a sideways final approach, but I trust the pilots and crew. I have to!
