Re: How to toughen up?
There are different ways to deal with this, Zash. And I hope you feel better soon.
You use your own judgment. Sometimes you think that the person should be ignored because they're not worth your time and energy. And other times, you need to put the person in their place.
Either way...the key is not to dwell on it after ward, this will drain you. The not dwelling can help build strength because you'll be using your energy toward most positive things that will enhance your development as an individual ;)
