yes, it's appropriate for people to move on with their lives once they are cured. it's also appropriate to stay and help others as long as one wants after too. both are good...i can't say i see any mental health risk in helping others, or any psychological aftermath scar problem, but that's just me.
i think people were just looking for a bit more hope and inspiration, maybe some summary posts? i'm not sure, i think though people generally understand once you're healed you're going to be moving on.
