Hi there, so yesterday I experienced a very strange thing. I was walking around in shopping mall and started to feel a bit of nausea and very light dizziness. So I sat down on a bench for a few minutes and everything remained the same so I had a lots of water to drink, then soon I become very weak and my vision became white and even more white to the point where I wanted to collapse because it was an uncomfortable feeling. I was still conscious and my friend was holding on to my arm while sitting on the bench. I could hear everything but it was a little fuzzy and I couldn t barley talk. I think it lasted for about 3 minutes in the state where I was just feeling very weak. I have passed out about 2 months ago, but that was a completely different experience and I didn t really feel any pain until I woke up with a bump from the table. This time I never passed out, I was conscious but couldn t really talk. I m also 17 years old
