FECES/FECAL ODOR-- BODY ODOR????AND FROM WHERE?

HI. I AM A 20 YEAR FEMALE.I USED TO BE A HAPPY YOUNG LADY. FUL OF LIFE AND HAPPINESS, TONS OF FRIENDS. I ALWAYS WENT OUT , HAD A GOOD TIME WITH MY FRIEND, YOU JUST COULDNT KEEP ME IN. BUT THAT WAS ALL BEFOE MY PROBLEMS STARTED. I WOKE UP ONE DAY TO THIS MILD MUSTY LIKE ODOR , IT TOKE ME A FEW DAYS AFTER THAT TO ACTUALLY REALIZE THAT IT WAS COMING FROM ME. I STILL THEN DIDNT MAKE THAT MUCH A DEAL OF IT, I THOUGHT MAYBE IT WOULD GO AWAY. HOWEVER IT DIDNT. THAT WAS A YEAR AGO. I USED TO SMOKE ALOT AND THATS WHEN THE ODOR REALLY STARTED. I WOULD LIGHT A CIGARETTE AND WHEN I WOULD INHALE THEN EXHALE THE SMOKE, A STRANGE ODOR AROUSE FROM MY MOUTH. THE SMOKE AROUND ME AND COMING FROM Y MOUTH DIDNT EVEN SMELL LIKE SMOKE, IT WAS THIS STRANGE NASTY ODOR. ANYTIME ANY ONE AROUND ME WOULD EVEN LIGHT A CIGERETTE THE ODOR WOULD EMERGE. SO I STOPPED SMOKING. THAT DIDNT HELP. THEN I WOULD JUST SECLUDE MYSELF FROM SMOKE AROUND ME , I WOULD LEAVE THE ROOM WHEN SOMEONE LIT UP.
WELL NOW MY PROBLEM IS EVEN WORSE. THAT ODOR NOW HAS BECOME MORE POWERFULL AND PERSISTANT. I NOW HAVE A FOUL ODOR OF FECES EMITING FROM ME. I DO NOT EVEN KNOW WHERE IT IS COMING FROM. I DO KNOW THOUGH THAT IT IS NOT GAS.BECAUSE I DO NOT FEEL IT. I DONT KNOW IF ITS A GI PROBLEM OR A THROUGHT PROBLEM. WHEN I EAT FOOD OR SWALLOW ANYTHING THE ODOR TENDS TO BECOME MORE POWERFULL. THERE ARE TIME THOUGH THAT THE ODOR STOPS, BUT THAT IS NOT OFTEN. I HAVE BEEN TO DOCTORS GASTROENTEROLOGISTS BECAUSE I HAVE STRONG STOMACHE PROBLEMS, LIKE , SEVERE PAIN AND CRAMPING. I HAVE BEEN HOSPITALIZED ALOT FOR GATROENTERITIS AND GASTITIS. YET THEY NVER FIND A REASON WHY IT HAPPENS. THE SAY I JUST HAVE REACURRING GASTRITIS ANS IBS. I TAKE PREVACID. I HAVE SRONG GERD BUT THE PREVACID HELPS FOR THAT A LIL. I HAVE HAD A COLONOSCOPY , A ENDOSCOPY , X RAYS, CTS, AND ULTRASOUNDS. THEY ALL COME UP NORMAL. EXCEPT FOR THE IMFLAMATION OF INTESTINES AND HEMMOORROIDS. I HAVE NOT YET TOLD THE DOCTORS ABOUT THE ODOR YET , IT IS VERY EMBARRASSING, BUT I KNOW I HAVE TO. I PLAN ON GOING SOON FOR FURTURE EVALUATION AND WILL TELL THEM THEN.--
THIS IS DRIVING ME CRAZY. I HAVE TRIED SUICIDE OVER THIS PROBLEM. I HAVE BEEN HOSPITALIZED FOR IT. I CANT LIVE A NORMAL LIFE BECAUSE OF IT. I NEED HELP- THIS ODOR ALSO CHANGES FROM TIME TO TIME-- I GOES FROM STRONG TO MILD, FROM PERSISTANT TO WHEN I BELCH-- FROM FECES TO MUSTY TO YEAST LIKE TO PLAIN OUT SEWAGE LIKE. ANY ONE WITH ANY COMMON PROBLEMS PLEASE HELP OR WITH ANY INFO--ANY THING CAN HELP-IVE GONE FROM BEING THE LIFE OF THE PARTY TO THE JOKE OF THE PARTY.....
