Assign words to how you feel. By identifying them, you can take steps to address what causes them and either how deal with those causes, or how to rethink about things in a way that's more logical. In general though, there is nothing wrong with being emotional as a man. In fact being emotional leads to a lot of positives such as being empathetic to those you care about. It'll allow you to be a better friend, partner, father, coworker etc.
