Just unbelievable!! I get a hit from google search using the string "what to do if a relative is showing signs of psycotic behaviour".
First, I have hardly discoursed on anything remotely pyschological on my blog (I think).
But more importantly, I don't understand how I qualify to answer the question. I have an opinion about relatives, but will save it for now (selfish reasons). Suffice to say, I would be most interested in knowing the answer to that very important question.
