Extreme nausea😑

I’m almost 10 weeks now and I’ve been struggling for over a month with extreme nausea and vomiting. I was sick pretty bad when I was pregnant with my son but it was easier as I wasn’t working or anything so I could rest when I needed. But now, I’m a single parent to a toddler and I’m a full time student with a practicum twice a week. I’ve lost 15 lbs now from being so sick and I go days as a time without eating. Yesterday it got so bad I ended up in the hospital dehydrated and dizzy. I just don’t know how to cope with this and I can’t imagine dealing with this for weeks or months longer😪
