I mean, it is just words. If some online troll's comments are gonna ruin your day, get ready for the real world in a few years, where no one gives a damn about your self esteem, and you have to grow up, grow a bit thicker skin and get on with your life and fight to succeed.
I'm not talking about real threats of death or harm, but just someone spewing off online or even in person.
Life is not all "touchy-feely", unicorns and kittens. Growing up, you learn to deal with idiots, asshole and those who don't like you (Yes, there always will be some that do not like you and are not your friend)....you learn to ignore that, shake it off and stick with the people that do love and care for you and move on through your life.
Seriously, thicken that skin and get on with your life and don't worry what the idiots say. You shouldn't have time for them.
