I Fainted

Another experience from me. Happened yesterday. I have been dizzy for 3 days now. Anyways so my dizziness was coming and going. After the class we were on the stairs and i felt it coming. My friends were speaking and they noticed it. They helped me and on the last step i was on the ground. They put my head between my knees. And then i managed waking up and comig round. We went to the dorm to have lucnch. And this morning i decided to go to doctor. It turns out my blood pressure is low (it is usually low but this time it is botheringly low)
