Being rejected is proof that you were brave enough to try. If you get rejected, you'll be stronger than people that don't try. I know, it's scary as hell. I've been there. What if it doesn't work out? You'll get rejected. If she laughs, you'll know she was not the one! You'll also be proud of yourself for trying and being brave. And what if it actually works out? You'll be so happy that you tried. Not everyone is able to do that, especially with a stutter. I recommend you go for it. The decision is yours after all. But I believe in you, really.
