Hi i only joined to ask someone this but at school today i was doing a science experiment and all of a sudden all the muscles in my body weakened and i felt like i was going to collapse, luckily i didnt. My eyes also blurred out, i dont know how to describe it but it was like a dark shadow around the outside of my eyes slowly caving in and making my vision more and more blurry. I was shaking so much, i couldnt tell anyone so i just leaned against the wall slowly walking to the teacher and asked sir if i could go to the bathroom. He could obviously tell i wasnt feeling well so he let me go. I have also had a tiny little headache that pops up every now and again.
