Going on a plane

I’m 26, and have never been on a plane. I’m deathly scared of heights, so that makes me scared of planes. I’m on vacation and just found out I’m 6 weeks pregnant, and have HORRIBLE morning sickness, which isn’t just in the morning, it’s all day everyday. Can’t keep anything down and so weak. Well back home is a 16 hour drive (me and the fam drove here). Taking a plane I would be home in 2 and a half hours, which everyone is saying is what I should do. But me being so sick and scared of planes and never flew before, idk. What is any of your opinions on this situation?
