Iv always been a tired child when younger i had insomnia which left me like a zombie during the day. im 16 now but when i turned 14 my tiredness went off the scale to the point i was popping a pack of pro plus to try and stay awake during a lesson for it to fail and leave me unwell. Im always tired, but if i get stressed or angry well generally negativily emotioned i begin to as i call it pass out, im completely aware to begin with whats going on still around me then i begin to struggle to keep my eyes open to the point i have to shut them because it is a losing battle, then i become weak and normally lean against my desk all the while im aware of whats around me, as i go deeper around the 3 minute mark, my hearing can still distinguish whats around me but there is sort of a white noise with it due to not being able to see and focus on the person talking. Normally when the teacher talks to me noticing what they say as me being rude and falling asleep i begin to come round but by then anything from 5 to 25 minutes have past and due to the distress of trying to gain control and "wake up" iv missed key points of the lesson. Iv tried as i said earlier pro plus, walking out of the classroom for air when the attack begins and i have even been reduced to stabbng the back of my hands or thighs wit a pen in hope that the pain will shock me out of it but it doesnt. This is really getting me down now iv currently just started my A levels in Maths,Chemisty,Physics and Biology, 4 tough subjects that require full co-operation to gain even a C in them. If you could help at all it would be so grateful.
