One thing about Asperger’s/autism that I think is hard for neurotypicals to understand, and is also hard for me to come to terms with, is that as an autistic person, my attitude toward socialization isn’t merely binary. The introversion instinct is incredibly strong, and it’s true that I can’t heal, rest, or reengergize without relative solitude. But that doesn’t mean I therefore never want human contact.
It gets even more complicated than that, though. If it were as simple as “I like to socialize a lot less than most people, but I do want to socialize a little,” that’d be relatively easy to manage. You just keep social interaction to a manageable level, whatever it happens to be For the individual. But here’s the thing: even human interaction that an aspie might affirmatively seek out is still fraught with discomfort, self-doubt, anxiety, and pain. It’s still exhausting, and sometimes dispiriting, unless it's particularly fulfilling in some way.
So when an introverted aspie is avoiding other members of his or her species, they may also be experiencing, at an atavistic, lizard-brain level, a longing for human contact, to feel assured that one still “belongs” in the tribe. And even when that validation is achieved in the most positive and affirming of scenarios, it’s still incredibly difficult.
This is the picture: Imagine a human being whose brain has developed differently than almost everyone they know. They may be incredibly intelligent or talented in some way or other (or maybe not!), and have a great deal of thoughts and feelings they desperately want to express and share. But the agony of submitting oneself to the evaluation of normal people, even in the most banal and benign circumstances, is often too much to bear, or at least too uncomfortable to make it worth the effort. When they do take the leap and try to mix in normal society, the energy drain is rapid, the stress is damaging, and the tiniest faux pas (real and imagined) is burned into their memories as scarring humiliation. So this human being, full of life and solitary, feels lonely, while determined to remain alone. Until the loneliness becomes too much, such that a new attempt is made.
I miss having a set of friends that I was comfortable with, that I could develop routines with, and rely on for that base-level validation that I was in the right species, that I had a tribe from which I was in no danger of being ejected. I have had that. A lifetime ago.
I don’t have that now, and most of my experiences after my life in professional theatre has been characterized by anxiety over being banished from whatever tribe to which I submitted myself, or else having no tribe at all, and cautiously yearning for one. (And not knowing that I was autistic in the first place.)
It’s not just that we want to be alone. But it’s the only way we know we can safely be.
