I've read somewhere in the net that bad breath can also be caused by psychological reasons. Is this true?

Thanks for all the advice guys.

Hello I'm a new member here, I am desperately seeking for an answer for my problem which is "bad breath". Everyday I brush, gargle mouthwash, floss and even use a tongue scraper but the problem still persists. I've been to the dentist to have my teeth cleaned. This problem of mine is affecting my self esteem and my social interactions with people. The girl i like in school is turned-off by me because of this. Most importantly, we're both on the same group in our class and i dont know how to face her. I hope somebody can help me.
