There are factors that impede recovery that are out of our control. Physical health being a big one. My disease spun out of control during my situation in large part due to the stress I was under. I am very resilient and am still recovering. Sometimes people do let go and look forward and think about plans but nothing can be executed until the mind and body is recovered and sometimes that is not complete in a 6-24 month time frame.
One can source any statistic to back up a blanket statement.
