Before you realise you are autistic (if you are), all you tend to know is the outline of your autistic self, as in, the shape that is left where you don’t fit in with other people’s experiences. It’s a bit like drawing a portrait of someone by filling in the background and leaving a space where the person is standing; what they call a negative space composition, in art terms. You get to know what you aren’t…but not what you are. Such an approach tells you a lot about all the misfitting bits but nothing much about yourself and that, in itself, can be a source of ongoing trauma because it can leave you feeling like a blank. Finding out you are autistic begins a process of filling in all the blanks and getting to know who you actually are.
