Im gonna be so real i think that people are scared to show anger from disabled people bc they are scared of seeing disabled people through a lense of the average person.
They think the most saintly thing you can do is care for someone disables but don't care about the emotions the disabled person themselves feel. Once you reach a certain threshold of disability, people stop seeing you as on the same level of humanity as everyone else. So the thought of a disabled person actually having negative emotion towards this help is shocking to them.
Sympathy is handed out to those exhausted and hurt from having to care for disabled people (which is fine), but not those whom may be in the process of mourning their own bodies/ability/mind. We can show a nurse/doctor having a breakdown, have entire genres of show and movie and book revolve around it, but if a disabled person lashes out thats seen as something much crueler in the eyes of the typical viewer. Its spoken about in the same vein of a dog who bites and thus "needs to be put down".
Why? Why? One day that could be you. You are not safe from one day becoming disabled. Nobody is.
