Hard choices. The "Should I do X, or it will hurt me?", "Is it worth feeling bad for doing Y?" related to the disease and its impact.
It's not about choice as in a healthy person having a selection of 10 fun sports to decice which to play in a sunny day.
It's about difficult choices, like "I want to do this sport activity today, but should I do it and feel depleted for the rest of my day? I should double think about doing this"
In other words, we could say that healthy people have more options, but sick people (of the variety of the article, not somebody in a come e.g.), have more hard choices on what to do each day, even simple things (e.g. play with the kids).
