"Allday sickness "

Good day ladies, I am pregnant with my second child. First trimester and I am nauseous all the time. Im starting work tomorrow and I can barely sit up straight for a few minutes then I have to run to the bathroom. I have a office job and just thinking about sitting at my desk all day being nauseous makes me want to crawl into a place where no one will find me. I have tried everything, medication, crackers,ginger, mint tea, cream soda. Nothing works. Any other remedies I van try!???
