Sense of Smell Changed,Gets Lighted headed and see's black quite often?

Rescently my Sense of Smell has Changed like im ALWAY smelling somthing,but no1 elce seems to smell the things i smell.and there usually not good smells like Fermaldahyde,or Brine. ect.

And another thing i get light headed and see Black alot.Yesterday i sware i past out Standing up.



I was in the Hallway for idk how long i just couldnt see anything it was all black.then suddenly i snapped out of it and walked to my room before i realized what had happened.



Im a pretty healthy 18 yr old yr. No previous health problems.I eat 1-2times a day. Nothing like this has happened before.Not on any medication or drugs.i dont drink caffine.

I'm thinking this is miscategorized.



Drink more water, the same thing happens to me when I get really dehydrated (minus the smell thing). And go to the doctor and get a CT Scan because odds are it's neurological and not that simple of a problem
