Flight attendants always warn you to put your mask on before helping anyone else, because you have to safe yourself before you can save others. The same goes when you're in a pool trying to help someone drowning; you have to be able to keep yourself afloat or you'll both drown. I've never been a good listener though so I'd crash and burn for you because it really doesn't matter if my lungs fill up with water and I drown from the inside out as long as your breath comes easier at night.
