All day sickness

Sumer

Hello! I'm currently 9 weeks and 5 days pregnant. This is my 1st pregnancy. I definitely underestimated morning sickness. I've been sick all day, everyday since week 6. As a teacher, I am really struggling. Looking for tips/advice. Also, I know it's different for everyone but, I heard that morning sickness peaks around week 9/10 then gradually fades? Is this true? I'm in a wedding in less than 2 week and I don't know how I'm going to make it
