First, consider the fact you can live the life you always wanted too live! when you know whats wrong with you why don't you work on them? Remember you got only single life, live it to the fullest!
My info must be wrong sorry only created this last night, I am 19 year old male. Thank you for your reply I will go to the doctors again and push harder as all they usual say is I'm suffering from depression and try and wave me of with depression tablets
Meant to say, you list yourself as female but say here you're a lad. So we can't know much about you.
It obviously wasn't the fact you were on vacation that had anything to do with this. But there are too many possible reasons for anyone here to tell you what caused it. You drank way too much, drank too little water, were out in the sun a long time. So, you might have suffered heat exhaustion, too much alcohol, you might have gotten food poisoning or drank water you weren't used to (assuming you're not from Turkey -- you don't say and list yourself as a female), you could have picked up a virus or bacterial infection, it could have been anything. That left you disoriented, which apparently triggered an anxiety attack. The thing about anxiety attacks is, they can be one off incidents or a sign of an impending chronic disorder. So now you could be suffering from a hidden virus or bacterial infection you picked up that hasn't been found or alleviated, or, and this is more likely, you conditioned yourself because of the bad experience of having that disorientation to expect to feel like that and so you do. The recourse of this isn't medication as a first treatment usually, that is generally when a disorder comes from an unknown source and is chronic, but therapy to see why you're holding on to this feeling of unease. And to make sure your doctors really really rule out any possible physiological cause. Good luck.
