Sorry if this has been adressed before

I can swim but I can't breathe properly while doing it. As soon as my face hits the water, I kinda panic. I know that I have to practice and get some swimming workouts in but does anybody have any tips about breathing? How do you girls breathe - out through the nose? the mouth? That's what I want to know....

I can't see myself doing 400m in the open water when I can't even do 25m in a swimming pool. I tried to relax and take deep breaths and long strokes but it's like my lungs just shut down and I'm screaming for air....

HELP

oh I'm going tomorrow morning and trying again. 25m at a time
