Dealing with hormonal changes while working

Hello ladies, I'm 7 weeks and 4 days pregnant. Today out of all days throughout my pregnancy so far I feel angry and stressed. As most of us are going through these hormonal changes, I feel waves of queesiness and so desperate for a nap throughout the days. The only thing is, I'm still working. Today I feel angry at my coworkers (not because they directly did anything to me) but I just feel like I can run out of my work place. I just want to take a nice nap, but because I'm payed hourly I won't get paid for the time I leave.. How did you ladies manage with pregnancy hormones & work? Did you ever feel that tug of war between leaving work and feeling the need to stay because bills need to be payed & your place of employment policies suck so you feel the pressures of staying for the money? Please share your experiences or even respectful advice .
