Suffering at work

Just started at my new job for 3months and I also found out I’m preg after I joined the company, so I’m 3months rn. My nausea is really bad that food smell, transportation and essential oil triggers it or even not doing anything I can feel nauseous too. Worst thing is my mentor at work is giving me a really hard time even know she’s aware that I’m preg and her usage of essential oil is giving me a hard time as well. I did feedback to my manager abt the stress and anxiety I am receiving from my mentor but tbh there isn’t much she can do plus she isn’t willing to extend my wfh anymore.. I can’t sleep well at night and I can’t eat well due to the nausea too. Idk what to do…do I hang on at work or do I resign? But resigning means short of income…. #advicepls
