send your mom and sister the posts you have wriitten here, maybe then they will realize how serious you are.another thing you can do is get your mother and dad in the room at the same time and ask them ,that will get to the bottom of it.Once there is 100 % positive you have bad breath start testing to find out where its coming from.
1 halimeter if nothing shows up get a gas chromatography test done.If nothing on that shows up get an organic acid test done and if nothing shows up get tested for tmau and if that shows up negative im sorry to say that there is a good chance that you have olfactory reffrence syndrome.
My point is people try to cure themselves without anyway of knowing if there cured and even if they get cured and people tell them that they dont smell they still dont believe them so treating olfactory first so you can rationalize when you actually get rid of bb is your first step. I can tell just by listening to you that you have already progressed to ocd.I know its hard to believe but its the ocd that is causing you all this grief ie not working or going out the bb is just the symtom that that triggered it.
So if you want to get cured first find out where its coming from and next cure your mental problems and the rest will fall into place.
Please take this as a positive message from someone that suffered for far too long
