. in high school i smelled like fecal matter due to the fact that i was lactose interarent and didnt know. whatwas the cause. i feel your pain especially since there all kinds of people in high school some nice most mean or not caring .even though most people wont be accepting of it and will want to end the convo quickly and nver want to talk to u again . but u will find a small gruop of friends who help u through it . until u find the cause of the smell
