text: what's this? hi ...usualy people ask the simptoms of an illness like what are the semptoms of cancer or whatever but i want to know the oppasit. and sorry about the spelling im in a rush. what could this be. lets say i was walking in my room getting home from collige when i got dizzy and fell over on the floor and didnt wake up for a wile? i'm sure you know the answer to this is you should see a health professional immediately.  there are several reasons you might get dizzy and pass out for awhile; you didn't eat that day, you have some type of virus, you're under stress - to name a few.  it could also be something serious.  don't wait, go see someone as soon as you can!
