I'm assuming that you weren't stressed at this point, so I must ask the question. Does everyone inflate their BC when they ascend? I was taught the opposite.
I also am curious as to how you began breathing water. Was their an equipment failure of some sort?
Glad you are alright.
If you were a fairly new diver, with only 70 dives, and at the start of a dive, at 10-15', with a flooded mask, couldn't see and started breathing water, I'd be willing to bet that you'd be jumping on the elevator up button also. Why would you assume she wasn't stressed? I can't think of a more stressful situation than to be breathing water and not be able to see. Granted, that isn't the normal ascent procedure, but when you can't see and you're breathing water, at least at that shallow of a depth and only a couple minutes into a dive, I think surfacing as quickly as possible, before you drown is a good idea.
I also agree that you need to practice mask clearing, not just clearing water, but taking it off and putting it back on underwater until it becomes no big deal, because sooner or later you're going to get your mask flooded. someone will kick it off, or hit it with their hand, or the strap may just break. You may be 20 minutes into a 100' dive when that happens, and if you start breathing water, shooting to the surface would not be a healthy choice.
Overall, I commend you for getting back to the surface and signaling the boat. Obviously, the DM was on the ball and as luck would have it, there was someone close by with medical experience as well. Glad you're OK!
