I like to think that I'm a caring, empathetic person, because you have to be to do this job. But there's nothing inspiring about cleaning up after a blind man who does nothing but moan and soil himself all day. There's nothing inspiring about stopping a man from beating himself because that's how he deals with whatever's going on in his head.
My skills lay in management, but I almost got whiplash dealing with the problems that would pop up over the course of an hour, let alone over a week. I'd have one client running to steal from the refrigerator, while a second is making a trail of feces to the bathroom, a third is attacking the television because he doesn't like the news ticker, and the fourth has fallen out of his wheelchair in a failed attempt to masturbate. You are dealing with the absolute base needs of humanity, and it will drain you.
Yo, Hollywood, if you're looking for Oscar-bait ideas, start here.
Severe mental handicaps often come with physical ailments, because at times human biology can be a cascading disaster of malfunctioning parts, like that 1995 Geo Metro you bought off Craigslist. Consequently, the medical needs of a single client can be mind-blowing. Many clients were visually impaired. One was blind, deaf, and severely mentally disabled -- to him, every second of every day was a terrifying riddle with no solution. There's a reason the play about Helen Keller is called The Miracle Worker, and that's because teaching someone who can't see or hear how to communicate is a goddamned miracle. Add in a serious mental disability, and you have a person living a literal nightmare.
