Nausea dues to stressful event ?

i wonder if any one can help or has any advice . in 2016 i went on holiday to barcalona, had a great time , now we missed our flight back home which caused me to panic (i have always been an anxouis person and was already anti depressents ) we were told there were no more flights to home so would have to get one to somewhere else in the uk which caused me to panic even more , at the time i sort of held the panic in and did not perticualy show it. now waiting for the plane and i begin to feel really nausous which continued when i was on the plane and when we got home. i have been feeling sick this whole time . at the begining it was intimittent nausea and now its just 24/7. i wondered if any one else had a similar issue and if this can cause something like this ? i have had tests and they cant find anything physically wrong with me . im getting very tired of this.

I am like you i am going to get hypothesis to try and help me out

i was out for food once and it felt like i couldbt breath and i was going to die, i have never been right since that day im always in pain but the doctors said im fit and well x
