This is certainly a quality most avoidants have, though I believe it is common among many diagnoses, rather than exclusive to AvPD. I have great difficulty opening up to people, as well, though not quite in the same way or for the same reasons as you, I think. For me it is more fear and the idea that it is bad/selfish to talk about my problems, and it sounds like it is more of an issue of showing weakness, unless I misunderstood you because vulnerability and fear are obviously related, even if slightly different.
It is very good that you at least recognize that your feelings about opening up aren't reasonable (such as realizing that you're sister wouldn't do anything to hurt you if you reveal something). It is still at least one step closer to being able to open up, even if it isn't helping you out too much right now. Learning why you do things is important, though.
As far as diagnoses, they serve mostly a practical purpose. Of course you cannot perfectly categorize mental illnesses and put people in nice, neat little boxes where every sufferer is exactly the same, but most psychologists, certainly competent ones, realize this. That is why no mental illness diagnosis requires the patient to fit all diagnostic criteria. The diagnoses certainly need improvement and revamping too, but that will come as psychologists learn more. Without diagnostic criteria, it would be impossible to perform useful research into what kind of therapies can help certain patients. So you don't have to take a diagnosis as a label, they are simply just useful to psychologists one some levels.
