Work vent long post sorry

So I’m 10 weeks pregnant with twins and the exhaustion/nausea is insane. I’m a nurse and I’ve been doing my best just to show up for work. There are different areas where I work that are easier and harder. Well today I was in the area where you are most busy and on your feet. I had to sit down and another nurse asked if I was ok and I said no not really I feel terrible and like my hearts racing. So she had me lay down on one of our stretchers and hooked me to the monitor and my heart was racing. She asked if it was better when I’m in an area where I can sit down more and I was honest and said yes🤷🏼‍♀️. So she has the charge nurse switch me to an easier area. So while I’m resting with curtains around me so no one can see. I hear the girl whose area I took huffing about it. Then I hear another nurse talking to the charge about how she was able to work when she was pregnant mind you she’s like late 50s and the charge is saying yea she’s on zofran. Then I hear the head of my department come over and my charge say “yea she said her heart was racing” in like a mocking voice. The head is like well what can you do? Stupid shit like that. Oh and to make it worse all of these people asked me in the morning with fake concern how I was feeling today. I’ve been living off crackers grilled cheese and apples with about a cup of water a day! I can’t function at home without taking breaks between brushing my teeth showering and putting clothes on. Then the head comes by and tells me I need to to drink whatever will stay down and all she could drink for 6 months was blue slushies. Whoop deee dooo. Nothing for me actually WANTS to stay down I wish I could drink a freaking blue slushy. The best I can do is very very slowly sip water so it doesn’t slosh around in my stomach. Idk what to do I feel like everyone hates me and thinks I’m faking 😞
