Flying fears while pregnant

I'll be 21 weeks when flying to England. I get super terrified during plane take offs to the point where I'm almost hyperventilating and my heart feels like it's going to jump out of my chest. My question here is, with all those high emotions, would this hurt the baby in any way? I know stress over long periods can have an affect on baby but was unsure of anything else. I'm only scared during take off or turbulance. Please don't judge me too hard on this, ftm and a little concerned.
