Inviting to a challenge is not insensitivity! Sorry if I wasn't touched as much as you were! people and their experiences are different and this doesn't make anyone more or less human. If it bothers you much I can share what I think:
Maybe it wasn't chemicals that improved her health, maybe it was having family members around after a long time. I wouldn't suggest removing drugs and replacing it with other chemicals using Google. If Google works over doctors, we should close down all medical schools then. Anyways, I think you should visit her more often. That makes her happy.
This has had a positive result. It is speaking about a success that has taken place. You must not have read it.
And no inviting to a challenge is not insensitive. No one said anything about your being human. You hijacked a post with this robotic nice post and then a challenge. You contributed nothing to this topic at all.
