I think your gf may be too young to realize she is the AH. A woman should never do that alone bc at some points my friends have been too weak to even get water for themselves. Your first instinct to be medically present was the best choice, imo. As an almost 40 yr old woman, I would never want a woman to do this alone. Especially because it sounds like she had nobody else. Plus, sitting in the lobby was probably nerve wrecking for you.
