Neverrr going out again omg

So I went to the grocery store today because we're supposed to be having a snow storm tonight! I was in there all of an hour...I'm standing in line and all of a sudden I start getting dizzy, feeling faint and light headed idk what was going on! I had to take a seat and have a drink; it got so hot I had to take my jacket off! Then there's a man standing in line with fish that smelled sooo bad! I think that's what set it off. I started smelling the fish and then this. After a while I was able to function again but idk what was going on! Terrible experience! I'm staying in the house from today forward! Lol. Has this happened to anybody else before?
