I went to give blood at a University blood drive... got the bag ALMOST full, and passed out. I started feeling really nauseous and sleepy, and then just went.
The nurse wasn't paying that close of attention, apparently, because it was a minute before she noticed. She unplugged me, and when I woke up, there were about 12 people standing around me, speaking a language that I knew but couldn't understand. THAT was interesting... I knew they were speaking English, but I just could not understand what they were saying.
They tell me that if you don't fill the bag all the way, they can't use it. So I went through all that and they had to throw the blood away. I got my Red Cross donor's card and the Blood Type on it is blank.
The worst part is that now I get flashbacks to that nausea whenever there is a blood drive. I can't even go into the same building as it at school without feeling like I'm going to vomit. It's sad.
