I think all this poster was trying to do was let you know YOU have the control in this situation. You can either tell your doctors what is really going on, or you can't/won't...If it isn't that simple, please explain. No one is trying to make you feel worse.
I don't think this poster is telling you how you are feeling, but it seems clear from your posts that you aren't happy, and they are just trying to give you alternate ways of thinking about it. It is ok if you disagree, but from my point of view, I don't think they were trying to be rude. I could be wrong, of course.
