Will I ever feel normal again?

I’m only 6 weeks 3 days and I’m struggling big time. My first pregnancy/miscarriage I was sick, but not this sick. Don’t feel like myself - super tired, nauseous, dizzy, out of it. I have to go back to work tomorrow and I honestly don’t know how I’m going to make it. Ugh how does anyone willingly go through this multiple times? Also major respect to the ladies who have HG because I definitely don’t and can’t imagine going through that. Y’all are the toughest people I know.
