Tears at work

May and June is a deadline month for my job and a little extra stress full. On top of it, I have a coworker that is out to make my job difficult. Today, two of the older office women barged into my office and made some rude and way too urgent remarks. I then got called into my bosses office and had some really minor bad news and I started balling, ugly crying.

She was SO understanding, but now I feel like a cliche hormonal pregnant woman... Even though without the hormones, it would have been rough.

How do you keep it I'm check professionally when you constantly feel emotional, exhausted, nauaeous, bloated mess?
