I'm currently at a crossroads

Amber
I apologize now for the long post, I really just need to vent. Any opinions are appreciated.
Ok so I'm almost 18 weeks and I'm sick as a dog with this baby. For 2 months straight I've been nonstop sick, even hospitalized. No medication or anything helps at this point. I had a breakdown after choking while being sick yesterday and my mom came to the rescue. She made a comment that she thinks my job is adding stress and making me more sick than I should be. I've had the rest of yesterday and all of today to think about it and I think she might be right. I work in a bakery. I work almost 40 hours a week, on my feet all day. About 3/4 of my week I'm by myself trying to clean up and wait on customers while also trying to stay hydrated from the heat of a dishwasher and no air. Also I should note that for the last maybe month or so the owner's daughter has been taking her frustrations out on me and blaming/yelling at me over how "awful the bakery is maintained and the mistakes being made." I've had no part in any of those mistakes that were made by other co workers and she basically accused me of using my pregnancy as a crutch to slack off and not give my 100%. I talked to my husband today about how miserable I am and that I think the stress of my job may be making me more sick and he agreed and suggested I just give my notice. Am I crazy? Should I just grin and bare it for the rest of the year basically? I'm due January 25.
