I had felt fine after I donated blood last year, went on with my evening until later that night when I woke up feeling ill. I ran to the bathroom and my vision was going in and out. When I was walking back to my room, I was just a few steps from my bed when my vision blacked out, and I dropped to the floor, taking my small shelf next to my bed with me. After a few seconds I came back and dropped myself on my bed. Got a cute on my leg and a small piece of my shelf came off.
