Feels like I’m getting sick

6 weeks pregnant and I overall feel like hot trash. So fatigued, my body aches, I have a headache, no appetite but I know my body is hungry or I get shaky, I also have bad anxiety so this doesn’t help. I literally have been laying all day with the air conditioning blasting. I don’t have a fever or anything but I’m trying to keep hydrated with water and Gatorade. Has anyone felt this or feel this way?
