Why do we get butterflies?

Is it not the best feeling ever! It's a feeling of excitement and fear. Your adrenaline starts pumping and your heart starts to race and your blood pressure rises! It's because your body is reacting to a stressor. Whether it be you're about to be chased by a tiger or about to go up to a girl you're interested in. Your fight or flight mechanism is kicking in. It's instinct it allows you to quickly fight back or flee and run in an instant. Don't worry! I get a thrill off of that feeling, I love it! So I ride roller coasters and go sky-diving so I get that feeling over and over! It's good, not bad! The way to get rid of it is just go for it! Go talk to her, it goes away the second you open your mouth to say something!
