Embarrassing Crush Stories

I have a crush on this guy called Manny, he plays he drums at church and last weekend we were at the same restaurant for a church event. I was about to leave and he walked in and I freaked the hell out. We made eye contact and I whipped my phone out and sent a text to my friend (we were texting the whole time so she could guide me on how to talk to him) and she didn't answer. I didn't know what to do so I hid behind my brother. awkward... leave your embarrassing/funny crush stories. (And some advice because I'm literally a potato)
