It's healthier to show emotions and get it out, rather than keep it bottled up. This is the reason I can only tear up and not proper cry yet as I didn't want to be seen in that state or seem weaker etc, from my early twenties. Now I try to let it out or work on it because nothing is wrong with crying!
I also killed off my feelings and emotions to make it easier to get out of my second (and horrible) engagement. It messed me up for a while and I advise against that.
