It's easy enough to say for one's self, but do you honestly feel "suck it up" as a response when you see it happening to others. I hope not, and when people want to respond to it happening to others, it is usually because they can identify, in some manner, with the emotions the other person is going through, whether by similar experiences or having gone through such feelings to a degree in other circumstances. If it happens to be your own child, those protective instincts can be mighty strong. "Get over it" is a rare parental response. I hope.
