Don't take this the wrong way, Isabeau, becasue I do NOT mean this to be a flame in any way.
Consider yourself lucky. The way you put this, it seems like this is the first time anyone has ever gone out of their way to harm you. I've got news for you. The majority of us have been intentionally harmed by another for no reason at all more times than we can count. It's become a normal thing in every day society. There are assholes out there, like me, that will say something to hurt you or upset you just because they dont like you. I differ from them in that I se the error of my ways and apologize, knowing that I hurt someone, and genuinely feeling bad for them afterwards.
Don't get so upset about it. It happens to all of us, and almost every other day sometimes. Get over it and get used to it.
