No I do not think he is a troll. I think he is genuinely attention-seeking. I think BlueInanna's analogy with adolescent behavior is poignant. And he genuinely needs support but cannot receive it. Look, he comes to a support board and finds a woman who is literally prepared to climb the Mount Everest with him (I am citing the thread on Goldberg Mania test). And what does he do with her? He blocks her. Isn't it irrational? That's why I was telling you on another thread that people are not in their rational mind and it is thus incorrect to state that sure, everyone protects his or her well-being.

To the OP: when you post a topic on a human board, you are soliciting input. Input may surprise you or may not be exactly what you expected. That is because this is a human board. If you are unprepared for this input, it is best to resort to algorithmic methods of information retrieval, without human touch. In other words, do a web research, go to PubMed and read articles there.
