I am a 19 year old male who has been having the same symptoms as the other posts. it started during my freshman year of college. i knew i could smell a hint of something sometimes and even when i looked around i could see some people's noses were red and sniffling and they would look at me. it's the most embarrassing thing ever. I dropped out of that college to attend another, hoping I could gain confidence but i don't think it's working. i asked my best friend but he says he doesn't smell anything, then again i'm not nervous around him. i dont know what i'm going to do. i tell myself before class not to get nervous, but in college it's different. it's not like high school where you know everyone, i cant explain it. if anyone wants to talk, my email is: firstname.lastname@example.org
having someone to talk to about it with the same symptoms would be really comforting.
good luck to all of you :/
