Nausea

I am about to be 8 weeks, and this nausea is just killing me. I don't throw up but I feel sick all day everyday, I feel like if maybe I would finally throw up if get a break for a couple of hours 🤢. My son has been acting up so bad lately and I just feel like I cant deal with him he's 4 months shy of turning 2. I'm always in a bad mood and I feel bad for him. Please tell me this will end soon? I didn't feel this sick with him, I literally have just cried from how sick I feel and tired and I just want like a 1 day break at least 😫 (I'm still super thankful to be pregnant again as I had a mc in May, but I feel miserable)
