Ill keep this really simple because I tend to waffle (who am I kidding, Im going to waffle).
There are two diagnostic books used in Australia that deal with personality disorders in a professional capacity. AvPD is in BOTH of them. So YES, it is 'recognised' here. Even if it wasn't, I don't think an educated professional adult would refuse to talk about it (?!)
Keep in mind though, many people with a PD can have "personality disorder" without it ever being defined - most personality disorders don't have a name, and OFTEN cross categories (not just comorbidities, which is different). This is because there's so many variations and combinations of symptoms that its just impossible to define every combination. PD is a combination of personality, inner experience and cognition, reflected against whatever is or isn't acceptable in your particular culture - not exactly something that simply will or wont fit into a category or that's easy to define.
The only TRUE (consistent) "rule" for diagnosis for a personality disorder, is, strangely, written pretty well on Wikipedia (for the record I hate Wikipedia) -
"...enduring maladaptive patterns of behaviour, cognition and inner experience, exhibited across many contexts and deviating markedly from those accepted by the individual's culture. These patterns develop early, are inflexible and are associated with significant distress or disability."
whether one set of rules is or isn't "recognised" is kind of irrelevant too. It doesn't mean that an individual who has a set of symptoms that are listed in a PD that is no longer "recognised" does not have a personality disorder. Its the categorizing that changes, not the existence of combinations of symptoms.
If you think your issues might have more to do with personality, and your symptoms are SIGNIFICANTLY impacting on your life (usually permanent / long term), a psychologist might be able to shine more light on the matter. Theres nothing wrong with suggesting to them the prospect of a personality disorder - they will soon be able to tell you if it is or not after a chat with you.
For the record, I haven't given any "advice" here other than go see someone. The above are definitions of PD as determined by psychologists/ psychiatrists, not myself, and anyone here can go onto JSTOR and do a few weeks of research to understand it for themselves.
