I have far too many... that's embarrassing in itself:
1. I was about 12, it was late 2015. So, for a bit of background, earlier on in that year I had started my periods and they were pretty bad at the time. I was sitting in a class, had started my period the day before. I was naive enough that I thought a small pad would be okay on the second day, and... stood up from the chair I was sitting in that class and... one of the worst leaks I'd experienced! I'm absolutely certain that other people noticed too!!! OMG I'm still embarrassed thinking about it now over 2 years later at 15!
2. Going back a good few years now, I was 9 (June 2012). I was having a lot of problems at the time with dizziness and fainting (which I still have to this day but not as bad as I did back then) and at my school we had singing lessons (where we had to stand up) every single Thursday morning. So this particular day I went to this thing, wasn't feeling well before I went in but again, I was 9, I was naive to what could happen if I stood up in a hot room while feeling dizzy. I was standing in the singing lesson (singing obviously) and suddenly started feeling all the signs associated with fainting. This was the first time I'd ever experienced these signs so of course I didn't really know, but at the same time I knew it wasn't right. The song finished and the teacher obviously noticed something was going on with me so asked the girl sitting next to me if she would walk me to the office. By this point I had subconsciously sat down in the chair was like half conscious at this point. Somehow I made it the walk across the coridor to the office. That was the point that I fainted, luckily I was close to a chair and right outside the office where the first aid people were. In my school they had like a bench in the corridor where anyone who walked past could see me, and the ladies got me lying flat on that. At this point... all the people from the singing lesson came walking past and saw me in one of the worst states of my life!! Was really embarrassing at the time, I'm okay about this one now as it's happened so many times. (I wasokay, by the way, after that day).
