10 days ago, i was sitting at my boyfriends house eating tea with his family. i started to get very warm, and had sweat coming from my head. my eyes started fuzzing and kept seeing dots and colours, and physically couldnt see a thing. (boyfriend asked me to pass him the spoon, and found myself feeling around like i was blind). i asked if i could go get some fresh air, wen i walked into the living room, i had to hold on the sofa because i couldnt balance myself and went to open the front door and didnt have enough energy and collapsed. im pretty sure i was unconcious, i woke up again and sat outside for about 10minutes. i dont no why this happened, it all occured within 5mins.. really scared me. can anyone help?
