You get sick, and don't get better. Over time this labor expands, devouring your free time and energy and hobbies and interests. Hours, weeks, months spent processing paperwork and making phone calls, waiting. Endless appointments and deadlines.
Its so depressing that its this bad without even touching on the strain of actually having a disability. Its a full time job just to deal with the means testing our societies puts up to prevent people from getting the help they need before you even consider the actual work of taking care of yourself
This labor will hit you at, get this, the lowest point in your life. When you are least able to do it, due to being disabled. Everything will take far, far longer and with more frustration than you expected.
Two fucking YEARS of constantly wrestling with the Social Security Disability system at a time when I had like ten seconds of executive function per day, all so I could get paid roughly what I made as an unlicensed first-year teacher at the lowest-paying private high school in Columbia, SC in 1985
