I recently had a bunch of mean people dump on me too. One example:
I am a volunteer soccer coach on a little local league for 8 & 9 yo girls. One mother accused me of purposely not notifying her that our soccer team had a game so that her daughter, who isn't the best, would not be there and we'd win. In fact I did email her, but in one of those email glitches, she didn't get it.

Meanwhile I am volunteering my free time for this. Plus, I rotate every kid in an equal amount of time, and in whatever position they want to try, because this is supposed to be fun.

I know that sounds small, but when you think about it, she is accusing me of being so cruel and selfish and mean that I would exclude a little kid from her own team just to win a game. I was super hurt by the accusation. So I told her so. She proceeded to yell at me some more, demanding apologies, and as for me? Her exact words were, "Get over it". I literally cried that night.

So my point is, we have no control over the people around us. We can hold our heads up high knowing we did the right thing. And then we have to do something nice for ourselves because we deserve it. I feel your pain and frustration!
