You're definitely not alone i was 14 when it first started including the rude commits,nose covers , lies even after i ask do i stink they so no and crazy thing is my mother suffered from the same thing and when i poop its exactly how you described i can honestly say that i don't have a good diet and i weigh 290 and I am 6.1. Iv'e tried body sprays bathing techniques iv'e tried it all so now i'm on an spiritual journey trying to seek the natural ways of eating and living because most or all of the food in america is totally horrible for our bodies especially people like us with sensitive stomachs.
