i was sitting outside with my friends and all of a sudden i felt really paranoid and everything got really really bright. the next thing i remember was my friends standing over me saying jessica, jessica! i was like what? they kept asking me if i was ok, and i was like yeahh? they said i was leaning over in my chair with my eyes wide open, they tried to talk to me but i didn't respond, and they started shakin me, they put ice on me, and were talking to me; i don't remember any of it. They said i was not responding, and lost all the color in my body. what happened and why?
