I can't remember if the term man up was used but I've definitely had phrasing like that spoken towards me and I never felt as if I was told to suppress my emotions. If you're a dude and you felt that way I'm curious as to what type of adult man you grew up to be, what's your relationship with women, what type of job do you have. I'd love to talk to your friends and see what they say about you because I've met men like you and 9x out of 10 you're all the same. Emotional issues, not the brave courage type, not a boss or manager, issues talking with women, weak spine and you know what that's fine but don't tell other men that "suppression of emotions" is a bad horrible thing because it definitely serves plenty men well
