Drained?

Is it normal in 1st trimester to be drained. Mentally, physically, and emotionally. I can't sleep. Barely eat. I honestly feel like I have the flu at times. I have zero appetite and absolutely zero energy. My head feels as though it's gonna pop. I don't want to get out of bed or off the couch, but then I'm restless when I am there. All in all I just don't feel good. Hubby doesn't understand it. I can't really explain how I feel "sick" I just do. 😔
