That makes me suspect that the mic is a cardioid, which is essentially a 
"half-sphere" directional mic. This generic mic type suffers from 
proximity effect, which boosts low-frequency sounds that are close to 
it. Breathe is a low-frequency sound.

There is no proximity effect at right angles to the diaphragm of a 
cardioid, so if you want to continue using it, orient it that way and 
place it several inches above and to the side of your mouth. You may 
need to turn up the gain. Several days ago, I posted recommended 
starting EQ settings. You might want to refer to that post.

Or maybe not try to put lipstick on the pig, and take K6LL's very good 
advice.
