One thing that really feels unfair is how society categorizes autism into "high" and "low" support needs, because often times being "low" support needs doesn't mean you need less support but rather that you can hide your struggles better.
"low" support needs Autistics struggle with alot of the same things that high support needs Autistics do ,we just learned how to mask to look competent, but it's never actually enough to live comfortably.
We can have strong sensory needs, meltdowns, struggle communicating, self harm during stimming or meltdowns, trouble interpreting people in social situations, problems with touch, problems with food textures, problems existing in public spaces, low overstimulation threshholds, immense energy depletion and hypertention from constant masking or surpressing our stims or behaviours that make us comfortable, high emotional and physical sensitivity, low tolerance for stress or confusing social customs, the same comorbidities that often acompany autism like dyspraxia, hypermobile joints, Adhd and learning disabilities like dyscalculia and dyslexia, IBS, endometriosis, asthma and so on.
The difference is often that we learned that letting it show is unsafe, or happen not to be completely nonverbal even if we self isolate and barely talk to others since childhood. This means alot of us live in constant hypervigilance and stress that we cannot turn off while also being isolated and dealing with everything by ourselves because others don't deem us disabled enough to deserve substantial support. Even though our lives often only function because we repeatedly push ourselves over our limits to do so.
The other part is how little support there is for adults aswell, alot of us have been missed during childhood and didn't get the help we needed, and once we are finnally aware of our needs , the system just does not scale . Especially for people who aren't visibly disabled.
Routs to support are inaccessible or stressfull, and the services that do exist have little understanding of autism beyond stereotypes. The lack of professional support is often shouldered by Family, but there are some of us who don't have a family to support us.
Autism is almost treated like a childhood condition ,rather than a lifelong neurological difference, especially in "low" support needs labeled Autistics, even if they have been diagnosed early.
