Many of us who have a job can tell you it's not easy. It's constant direct and indirect comments on a daily basis. And you have to do your job better than anyone else, because they're trying to find some excuse to get rid of you. If they don't want to fire you because they don't want to pay unemployment, then they'll try their hardest to turn the screws on you so you do quit.
Try to find a job where you're not in the same enclosed area 8 hrs. of the day. If you can keep moving from area to area, that would be good.
Start on one of the diets of fruits, veggies, and little meat people are talking about. It works but you have to give it time. It will take 1-6 months to get rid of the odor but you have to be persistent and not quit.
