smells bad but can't smell it

please help me
im 16 years old female, no't overweight im virgin. I don't smoke i don't drugs, i noticed the smell when i was 9 years old.
i shower everyday wear clean clothes and still smell bad. deodorant dose not work. i tried everything!
there's something i don't understand i can't smell it, but when people sit next to me the cough, cover their nose,give me those horrible glaces at the the class when the teacher comes in she yells open the windows and the air conditioner, and everyone just stare at me.
my mother and sisters says i don't smell but my dad says i do

i think the smell is coming from my armpits, because whenever i rise my hand people start coughing.

im gonna commit suicide if there was no cure for this i can't take it anymore people don't treat me like a human
