"Belittling others doesn't make you superior"

Okay so I'm actually experiencing life at a whole new level right now and I've noticed people start belittling you for the dumbest reasons-what you need to know is that a person can't affect you in anyway and that there probably deluded or sad and being mean to others makes them happy ,don't let them make you feel unworthy of yourself.The best thing to do is to ignore them and carry on with your life!
