Just need to vent

Monica • My husband and I are 36 and 35, high school sweethearts, married in 2005, son Gavin born 11-27-15. PSU grad, work for small newspaper as a reporter.
My co-worker is all about drama, and she tries to one-up everyone all the time. Ever since I announced my pregnancy, she has been stressing about how things will work when I go on maternity leave (not my problem) and I swear she is mimicking my morning sickness and other symptoms. Last week I had to leave early due to severe nausea and vomiting, and tonight she left early, saying she had to throw up. Seriously? And every day she complains about a different body part bothering her or how she can't stop peeing. Meanwhile I suffer silently and try my best to ignore her. Rant over, lol.
