That comic is pretty accurate.
I've personally always described that layer of protection that allows you to no longer react to things emotionally as a mask.
And it's REALLY unhealthy to have a mask on at all times. Your brain requires an outlet for the emotions you feel, and reacting to what you experience is supposed to be that outlet.
And if you no longer have that outlet, your brain will slowly adapt to it, destroying your capability of feeling emotion entirely.
