What people mean by "man up" is "leave me alone with your problems, I don't want to hear them". People (except your close family, and sometimes not even them) don't really care about you, they care about what you can do for them. Some will feel pity for you but this doesn't change anything so it's better to not mention your problems to a lot of people.
Good observation. I myself, over time, have seen some of these "man up" types lose their heads completely when it comes to a relationship brake-up.
Though, if I was to offer the "man up!" advice in this situation, would it be insensitive??
I understand long term relationship break-ups can be traumatic. I've been there.
But the wounds eventually heal.
Hair loss at a young age (20's) is a blow that will stay with you a lifetime.
In fact, in a lot a cases, you will carry that bitterness with you into old age.
If you have a skull structure that can suit a shaved head (only about 20 percent of balding men) then good luck to your blessed ***.
If you don't then get used to being at the bottom of the social ladder.
Most of society really is that shallow and small minded to treat you according to the image you project, through no fault of your own, mind you.
No....that concept takes WAY too much intellectual work for the average forced fed (their tastes and beliefs) robot walking around out there.
