Can’t eat

Everything tastes and smells horrible! Not metallic like I see others posting but like everything is rotten. Right now I’m down to apples and granola bars. I’m sooo hungry. I’m weak and the smell of everything makes me nauseous. My roommate has the slow cooker going and it smells so disgusting and strong. I’ve been locked up in my room with room spray and a candle because I can leave without gagging. I’m having a very hard time. I love food and love to eat but I haven’t been able to for almost two weeks. I’m only 7 weeks pregnant and don’t know what to do anymore. Has anybody else had this? How did you get through it? When did it end?
