Hi, I have suffered two panic attacks in the last year. They were very clear to me that they were panic attacks, I couldnt breathe properly, I felt sick, I couldnt move, my head heart for a while after. A couple of days ago I was stood talking to friends, all of a sudden i felt like i couldnt see or talk the feeling of losing my sight intensified quickly and i collapsed with my friend catching. Similar to the panic attacks it took about ten minutes of quiet to come out of. I am unsure if this was a panic attack it came on much quicker and i was fully unable to stand. I dont remember exactly what happened but apparently i looked fine and had my eyes open the whole time. I am 5 6 weight 11st12lbs. 23 years old and i eat pretty healthily.
