There are things I can't do or need extra help with weather or not NTs see it as the norm. If I forget to eat due to being absorbed in my interests, if the sounds of the birds or the grass on my feet overwhelms me, if I can't ask for help when I need it, if my motor skills lag behind.
it does not matter if ASD was taken out of the DSM tomorrow I would still struggle and more over if ASD is not seen as a disorder or disability I lose out on the services I need. Every single service I get is due to somebody else thinking I am disabled and they are not wrong I need the help.
I think the view that autism is just different brain tends to come from people who can be more independent easier or were diagnosed after they already made a life with children and spouses and jobs and that's ok it's just a different perspective but I will still call myself disabled because I am and I guess I am disordered too even if the word has a negative connotation for me.
I have many many positives that NTs do skip over but my world is contained to my house or even just my bedroom where I don't feel autistic in the way that I notice the difference and even then I notice when my self care and ADLs suffer without support.
I am lucky to have at the very least one person in the world who understands me (my mother) but I have to live beyond her at some point and I must accept the disabled parts of me. I don't suggest ignoring all the positive attributes we all have but you miss the fundamentals when you skip over the negative. ASD criteria states "Symptoms cause clinically significant impairment in social, occupational, or other important areas of current functioning." this is a criteria that has to be met your life has to be harder without that you are just quirky or eccentric.
I would have not spent all that time in OT if I didn't have to, I would not have gone to so many therapeutic schools and special ed rooms if I didn't have to, I would not be moving across the country if I didn't have to, but I have to I have no other choice I need the help. That's a disability...that's a disorder. There is no shame in that.
