Try to concentrate visually on something initially as you are going under. This worked wonders for me while I jumped out of planes with the Army and actually assisted me when I became certified. This allows you to go under not looking at the mask and when you quit watching the item (your hand holding the inflator is what I used) you are already under and breathing normal. Don't feel illogical, just like jumping, breathing underwater goes against everything that we are taught as kids. It just takes a few tries to find your way. Welcome
