Not sure if this is the right place or not.......

I'm good at stressing at the best of times, it runs in the family!! about 10months ago I was on a short flight that needed an emergency landing due to smoke filling our cabin. It was very scary at the time & has put me off flying for ever!!!! I was always a nervous person on a plane to start with.

Problem is I have to fly from QLD to SA next week for a Wedding...with only 4.5wks to go then I really don't want to stress, but I can't stop thinking about it. I never wanted to go, but we are very close to this couple & I didn't want to not go just for my fear of flying. I'm stressing I'll put myself into premature labour due to me stress over it

Does anyone know of anything at all I can take to keep me calm?? anything??
