It gets even more complicated when you add things like Williams Syndrome into the mix -- WS causes you to feel safer with 'friendly' people and so you're typically more social not less, but is often comorbid with autism and so can make diagnosing autism more challenging (in my case it was mostly because I had an abnormally high IQ and sensory challenges). But I am highly empathetic, have some talent for music and writing and was basically a TA for most of my school years, while still having most of the autism-related issues such as RSD, demand avoidance, meltdowns and so forth.
