Don’t make a bad thing worse by continuing to be upset about it. Get over it and rise above it.
From time to time you’re going to be inconvenienced, insulted, distracted, taken advantage of, or worse. Quickly, decisively deal with the situation, get some distance from it, let it go and press on.
If you’re not in a position to do anything positive about it, then accept it. Direct your focus to the good and useful things you can do.
Of course there are going to be things that will upset you. However you have nothing to gain by continuing to remind yourself how much you dislike them.
Choose not to waste your time and energy assembling a collection of grievances. You have so many better things to do.
Spend each day living and doing, not whining and complaining. Rise above the foolishness and live every moment on your own best terms.
