bad BO

More information: 
hello, I'm 24 years old and I have this BO problem for more then a 12 years. I tryed everything (deodorand,antipespirants,lime,soda,vinegar..) nothing works for me. Also my feet starts to smell bad. The second problem is that I CAN'T SMELL MY OWN BODY ODOR (ARMPITS AND FEETS) I can put my nose to armpit but I can't feel anything, ( just some weird smell). What is wrong with my nose? My bf told me that I smell bad even after showering and I can see other people faces when I passing next to them. My sweat marks are also yellow when I wear bright t-shirts, and sometimes my sweat under my armpits is white and very thick,especially when is some a stressful situation on my work.. HELP ME
