My therapist, who specializes in this area, strongly suspects I have high functioning autism, although she insists that people refer to autism as PDD/Asperger's (depending on your level of functioning).

I have sensory problems, flat affect, flat vocal tone, eye contact problems, social issues, I share typical Asperger's interests (math, science), etc., but my IQ is well above average, so I would fall into the Asperger's category if anything.

I am not diagnosed with Asperger's mostly because my parents told my first psychologist that nothing was wrong with me in any way, shape, or form (i.e., they said no to bipolar or any of my other Dx's like anxiety and ADHD). I had them fill out a form for the lady and they just denied everything. Then the psychologist (figuratively) had to toss it in the trash because my parents were useless for giving her information. So I literally have no one to vouch for me if I want to get an official Asperger's diagnosis.

But anyways, enough of that... Some people are highly sensitive people in general and eye contact issues can be due to anxiety. You would be surprised to hear how much anxiety can actually mimic Asperger's.

And btw, "not wanting to talk" is not really an autistic trait. People with autism have problems interacting/connecting with others and may not want to talk because of severe social backlash they have endured in the past, but that's reactionary and is different from being withdrawn and/or anxious about talking. Most people with autism are social (or at least want to be social), even if they prefer to be alone.
