I'm glad that you've suffered no lasting harm, but please do not overgeneralize to a claim as strong as saying that without social expectations others would respond similarly, because this can lead to people thinking that those with persistent problems after an isolated trauma are how somehow perpetuating their own problems through their attitudes. This is contrary to everything we understand about how humans respond to stress and trauma on a lifetime scale, and in particular contradicts the glaringly strong evidence from the CDC's Adverse Childhood Experience dataset that lifelong resilience in the face of stress is dramatically reduced by early traumas.
Unfortunately, my experience is more first hand (survived a nearly fatal accident as a toddler that has had lasting impact on my life). But I recall the CDC's page on the study having some good jumping off points, and I think I first ran into it via this series of articles: http://www.huffingtonpost.com/jane-ellen-stevens/the-adverse...
