I hate my life...

whatever was in the video, I'm sure you had a reason for sharing it.
if someone has an issue with it, FUCK 'EM
if it's from your family, maybe not fuck 'em, but...hm...
well...Lemme put it like this: If you are threatened to take whatever down or things might happen, stand tall, defend yourself, and let the small things be gone.
small things like a CD, laptop, TV, ect.
unless of course it's literally destroying your family life, then why would you post it in the first place?
if it doesn't and 'embarrasses' someone in the family, they will get over it, and move on with life
that's how MY family is anyway... if your mother can't handle what's in the video and has to make a minor threat to get you to get rid of it, then she has issues with handling with embarrassment.
now then... I think I've typed up too much of a storm, don't take this he wrong way, you'll feel better soon, ciao
