Hi, sammy. Along with all the other good advice given here, do you mind if I ask how old you are & whether you smoke or have a job where you breathe in any pollutants of any kind? The reason I ask is that there is another condition which affects the lungs, called COPD but this usually occurs in older people. It is often mistaken for asthma, but can be diagnosed by a simple breathing test called Spirometry, at your surgery. Having said that, yours sounds more like a mild panic attack, which is easily treated. Have a nice holiday & go & see your Dr when you get back! Kx
