I have been down in esteem and embarrassed for 19 years now, what should I do?

Joseph, lots of people suffer from halitosis (bad breath). Several things can cause this.

The most common is tooth decay, so you need to brush your teeth carefully and see a dentist at least once a year to get your teeth descaled and any decayed teeth treated.

Tonsil stones are another, less common, cause of halitosis. These are little pieces of food that get caught in the tissue of some people's tonsils and become calcified. You need to get your throat examined by a doctor to see if this is the cause. If it is, you will be given advice on how to deal with the problem.

Thirdly, it can be a digestive problem. A medical check-up will establish whether this is the cause too.

It sounds as if you're still quite young, as you mention going to school. Lots of young people get very sensitive about problems like this, and may even exaggerate their own symptoms in their anxiety. Other young people can be cruel too. Try and get some medical and dental help. I'm sure your problem can be solved.

Suck on whole cloves, they have a pleasant strong smell, and you can carry a little bottle with you.🎁

Hi, see my recent post -- in my case, reducing my intake of foods and drinks with sulfite or sulfite preservatives has help with my issues of, 

I'm assuming, a similar nature. For me beer wine processed meets brewed drinks etc I try to avoid especially some long life products that are full of sulfites  Also dried apricots  etc black tea I think is dried with sulfite where green tea seems to fine . Strangely, too much intake of sulfite ladend foods

causes me to breath out something similar to hydrogen sulfite -- rotten egg

gas -- as weird as that sounds. Your case may or may not be like mine but all the best
