If it's about myself...YES.
I don't like revealing things about myself unless the person asking the question is in a position where they can really understand where I'm coming from. I have major qualms about revealing certain parts of myself around the majority of people, because I every time I've done so, I have been ostracized, bullied, snubbed, and generally avoided by people. For instance, I am comfortable talking about my autism-related endeavors with professionals I meet in the field, families of those with ASD and with others with ASD, but not around my peers unless I am convinced that they are that open-minded to accept me completely and not patronize or pigeonhole me.
I also hate being put on the spot or being the center of attention unless people are respecting me for it... for instance, when I speak about ASD I am completely comfortable because it's a special interest, but I am anxious in general social situations where you are expected to be reciprocal in conversations and the topics involved are more fast-paced and spontaneous.

Given a “tentative” diagnosis as a child as I needed services at school for what was later correctly discovered to be a major anxiety disorder.
This misdiagnosis caused me significant stress, which lessened upon finding out the truth about myself from my current and past long-term therapists - that I am an anxious and highly sensitive person but do not have an autism spectrum disorder.
My diagnoses - social anxiety disorder and obsessive-compulsive disorder.
I’m no longer involved with the ASD world.
