smell of poop

Something is wrong with my body, it seems that I smell like fece. I take a shower everyday and have done some crazy stuff to fix this problem, but nothing seems to work. It has put me in a depression state for about 6 years now which destroyed my high school years and now my college years. It ***** because I need to go to class and there is where it is most noticed. I've heard many people having the same the problem and I know how hard it must be for them. If anyone need a friend then i'm here. Sometimes this situation just seem to have no real explanation to it, but i never did smell like it in the first place until 10th grade. This is really weird, but it is taking a lot of toll on me. Girls are hard to get when you can't even get near them and hearing all the shyt people say when they don't even know what is really going on. Help!!!!!
