Indigestion. With me for so long.

I have been suffering from a strange Problem.When i stay at place,it smells like sewage around me,the smell is following me.It is present for few days ,there is absolutely no smell on some days.My mouth smells bad and so my arm pits.Whenever I eat Non-veg,Egg,or any spicy foods my stomach upsets.People rubbing their nose whenever i went to a place and some people are joking behind me and making fun.One year back i used to eat non veg very often,but now i gave up every thing.from one year this problem is severely haunting my social life.I stooped going to theaters ,restaurants and attending for seminars and gave up everything .when i walk around drainage that smell persist with me for so long. I tried so many medicine .Problem is not identified and cured. please give me suggestion. Unfortunately my friends and family didn't smell but rest of the people did.I don't know is it real or My inferior complexity.
