Morning sickness

I’m 7 weeks pregnant, and my morning sickness lasts all day, literally never ending. I wake up, vomit uncontrollably for about 2 hours, and then it dies down to about once an hour. I’ve been missing school due to this the past 3 days but I can’t keep doing that, I’m a senior in highschool. What should I do? I really don’t want to do homeschooling or anything, I don’t have good enough internet at home to do online. I just feel like my only option is to miss more and more school at this point. I haven’t talked to any school officials yet because I haven’t been there, but what should I say to them/what should I try to get out of it? I’m just lost, and honestly, pregnancy is making me miserable.
