I approached a girl who was walking the opposite direction to where I was walking with her headphones in. I pulled my hand out infront of her and leaned in as if I was about to speak but once it seemed as though she wasn't slowing down, I froze. She kept going till about one or two steps past me which is when she took one of her earphones out but at that point I kept walking on.

As you can tell im a complete beginner however I honestly don't know why I froze. My heart was racing like crazy! and I wasn't able to approach any other women that day. Maybe im not made for stranger approach? How do I stop my heart racing crazy and the freezing?

Is there anyone that can help me?
