Oh, no, I don't think it was poorly worded at all. Says what it needs to, doesn't it? "I'm going now, I don't know when I'm coming back, please don't talk to me." The only misinterpretation happened when absolutely everybody decided to do the precise opposite of requested. But that wasn't any wording error on your part.

So the question remains. Why did they all flock? If there's nothing to worry about? Strange, isn't it.
