No one takes me seriously 🙄

I'm pregnant in my first trimester and literally everyone thinks I'm overreacting. I'll say I can't eat or drink anything because I just throw it up. Them: "oh eat some crackers." I say I'm exhausted. Them, "I work all day and YOURE tired?!" 
I can't win. I'm nauseous all day long, heartburn like a birth, my throats is on fire from throwing up stomach acid and no one even cares. My doctor doesnt even seem to care. What do I do? This is absolute misery.Â
