The issue is that if you become a master at masking because of decades of experience, who can tell if you are truly on the spectrum or just struggling with certain things?
I am facing this issue, I don't know if I am on the spectrum or not because if I am, I have reached a point of being able to mask it almost completely. and if I am not, then I guess I just had a bunch of social and sensory issues that just took me longer to understand and learn to manage.
An ASD diagnosis costs about $3K and any non ASD medical professionals seem to not realise my masking.
I am left with either spending $3K or self diagnosing, both of which feel wrong, so I am stuck in neuro classification limbo.
