Hi Leanne,
i hope you are feeling a little better. I really feel for you- i have been sick due to anxiety before too and it's a terrible feeling. I was on a train home from work about a year ago and every time i swallowed i felt like i was choking. There were so many people around and i was getting more and more agitated. I had to rush off the train at the first stop i knew and run to my dads office to be sick!! I really didnt want to make the rest of the journey home but my dad came with me and i found that sipping water helped a lot. I really hope you are OK hun.
Take care
Love Em xx
