My sensei from way back (ex-Singapore police and reserve SAS) drummed it into us "First option..walk away, second option.. run away...if options 1 and 2 fail, take as many of the feckers down with you as you can"..thankfully, I've never had to use any of those options.
With regard to the weightlifting videos, just try and remember your coaches are not judging you as a person, they're critiquing your technique with a view to improving it. 👍
