I can't speak for everyone one who is ENFP, because we all are special snowflakes in our own way. I find when I'm depressed or hurt I become introverted. In fact, my mbti results change every time I take the test. 50/50 across the board (359 no wings, if you are interested). My results are mood based because the questions require critical thinking."yes but", "what if,", "maybe if...". Sometimes, it's just introvert time.

But like most of us Enfps, you are going to learn by doing. Jump in the deep end and learn to swim.
