Hi, im a 13 year old girl so this morning i got up and went to take a shower i felt fine and randomly I felt like i was going vomit and then I couldn't hear anything and my vision started to go black which usually happens when i get up to fast and only lasts a few seconds but it didn't stop and I felt like i was dying and I tried to sit down but I couldn't see anything thw next thing I knew i was laying on the ground in the shower and had no clue what happened and why i was there i kept telling my self in my head that i had a soccer game later but I just couldn't comprehend it and i got my self up and layed down in my bedroom and now i fell fine just a little shaky and i havent told my mom im 13 btw and i am scared it's going to happen during my soccer game.
