Being a male, the stereotype is to stfu it's unbecoming, and due to intense issues throughout my school life it's become a common practice to unstead of becoming sad, give them a death glare (or that's what people call my "I might kill you tonight" face, and when I say people I mean one person but I Like the name).
Though what I do isn't healthy, because I don't actually kill the people the emotion just gets bottled up. My point is whatever is the best way for you to release your emotions is, do it. If that's crying, do it, if it's violence, direct it to a punching bag, and if it's bloodlust, find a new outlet.
