In the case of revenge porn I'm not sure that's really cyberbullying. I think that's more like you did something dumb and you live with it or you don't. That's your choice. Hey, when I graduated high school we had a big ole party had some liquor, I whipped my dick out in front of everybody, broke like 3 tables and chairs by stumbling into them like Peter Griffin and threw up all over a living room. Yeah that was a really silly stupid moment in my life, got teased about it for literally years after but I didn't let that define me. If you let single isolated things define you like that then maybe you should seek professional help.
