Often the the DIS in disability grows larger as you get older.
For me it was obvious because by 16 my vision was too bad to drive so I was suddenly different from everyone else. At 24 when I was too mentally ill to live on my own I was again different than everyone else (back then there was still a lot of stigma around people living at home). I never found a real job after that largely due to disability based prejudice. Failing to live on my own the stigma grows with each passing year.
Adulthood is no picnic to those of us with disabilities because adulthood itself is marked by milestones like having a car, a job, a place, a community that accepts you, etc.. and a lot of us don’t have any or many of these things. Childhood has its own pitfalls but for a lot of us it was better (except for those who were bullied all the time).
