Wow, I'm really sorry to hear about your situation. Ive also had problems with body odors for a long time. I found this site and i think it helped hide the fecal odors that were emanating from me. You should check it out also and see if it helps. http://www.pilulepet.com/en/
Damn.. sorry to hear you have to deal with this. I have for 3 1/2 years, and it started when i was going through many rounds and changes of antipsychotics and antidepressants and feeling hated by everyone around me and it just started happening. Painful heat and sweat and then smells.. it was so difficult to make sense of it. Never was there any physical movements or processes causing it. The social ramifications.. wow. Here for you mate, though it seems like no one will ever understand or do much in response other than tearing you down and stomping on you.. gotta forgive, they feel they are doing whats right, but they dont know what you are faced with. Here for you, hope you are doing well
