This nausea/vomiting is killing me!

Just • 2 girls & baby girl no3 on her way 😘
I was really bad with my dd as well but at least with her I was sick all day this time I have nausea all day and sickness about 3-5 times in the day. In the morning (like now) I have to get up early eat something so that I can be sick at home then eat again and not be sick at University. I feel so awful on my Dd though because I feel like a zombie especially yesterday that was really bad day. I just wanna cry coz I know when I stand up in a min after typing this im gonna throw up again ?
