You did the right thing by calling her out on her behavior.
I remember when I first arrived to the white board, your post was one of the first responses I received and it made me feel very welcomed and was helpful as well for navigating the sites.
I try to peek in on the white board when I can, I haven't been on as much because most of the days I'm laying down nauseaus to the max, but it's sad to see that there isn't as much solid support as there once was. I honestly don't know what I would have done without the white board, it was a lifesaver and brightener for me during very dark days.
I know IF can bring on alot of emotions, bitterness, sadness, frustration, etc but taking it out as an anon poster/cyber bully towards someone trying to be helpful and supportive, isn't the way to deal with it.
It seems like this person doesn't make an appearance often, I wonder what triggers her?
You didn't start the fire....lol. Don't let it get to you.
