I'm so impossibly shy and nervous? I would really appreciate some suggestions and some help with this guy?

I know exactly what your going through because i am also incredibly shy. What i do to stay calm is to remind myself that this could be my one chance to go out of my comfort zone and be myself around a stranger(whom i might like). So i really think you should try not to think about it too much and go for it. you will be so happy once you do!:) hope this helps
