I don’t know that I could say whether it gave me anything emotionally that I might not have otherwise had. I’d like to think I’d be as patient or understanding regardless of disability.
I have had several “perks” from being disabled though.
In high school, my last 2 years I was allowed to leave classes 5 minutes early so I could walk to my next one without anyone else in the hallways so I wouldn’t be knocked over (I only started using a scooter full time when I went to college).
I was allowed to take the SAT at my school rather than an official testing site and was given a bunch of extra time (which I refused to use). My guidance counselor trusted me so much he let me set up the whole thing and moderate it myself.
In college, I was given the handicap room at my dorm. It was usually given to seniors as a perk as it was 2 separate rooms with its own bathroom rather than a shared suite with 4 people. I got to use it all 4 years.
I got my last job from a minority program at my company. They brought out about 100 minorities to a job fair for the company where we got to interview with all the different departments. I got a number of offers around the country from it. It was a bit strange being classified as a minority as a white male (and I felt a bit bad when the coordinator of the event told me I was by far the best qualified person there for most of the jobs, oops). It was a fluke that I got invited at all. I was contacted by a manager at the company for a job and when I was talking to her I mentioned it was hard for me to travel because of my disability and that’s when she told me about the event and signed me up for it.
And handicap parking is always nice, mostly for the space for me rather than the distance.
