Hi, my name is Andrea, I am 19. I have a history of depression and anxiety . Since I was 13 if had random episodes of fainting if you could call it that. I don t actually lose conciousnous. It comes on out of nowhere sometimes, I have a funny feeling, I don t know how to describe it but. Know what is coming. My body starts to flush and my vision turn red and splotchy until I can t see anything, my ears must swell shut because I can t hear anything. I know at this point that if I don t lay down I will fall, my body is weak and can t hold itself up. I lay on the ground feeling extremely nauseous waiting for my vision to come again. My body becomes hot and I sweat all over my body, then it fades and I become extremely cold. This last only a few minutes. I have been told I lose all co our in my skin . It Lasts only a few minutes usually, but feel weak for half hour after. It sounds like heat exhaustion but it has happened in the cold before too. Any help would be great thanks.
