>third implies that the victim is able to overcome the problem and let it slide off of their back.

I don't think she's saying that. These events are serious, but they're just one event among a lifetime of events. If you needed to use a wheelchair to move around, you would want people to respect your mobility limits, but you would emphatically want to be more than just your wheelchair. This does not imply an expectation to let that you should let the injury "slide off your back," but it does mean that it's your life and we should all let you decide how to deal with it. Don't push your understanding of how I should feel on me.

The author is saying, yes, these things happen and they're bad. But let's not lose sight of what we are here for. We are all more than our injuries, and even (especially!) when those injuries continue to haunt us we should strive to do more than focus on them.
