I guess it should be addressed. I can reach a logical conclusion that I should not be, for the same reasons you state. I in fact feel like an almost completely different entity than young me. And yet I still wince a bit to think of this stuff.
But should I see a therapist to address my feelings about crying due to the results of a children's athletic competition? I guess I ultimately wouldn't care if my friends knew that one, but I can empathize with people that would feel super uncomfortable.
