Yo.

Basically here's the deal. I'm 17m and have had anxiety (solely around girls) for the majority of my school life. Over the past few months I've started talking to a girl at my part time job who also happens to go to my school (She's a year younger so we don't have classes together and my campuss is huge so we barely see each other anyway) and I think she's into me. She's cute and our personalities go together pretty well. We talk on social media and she seeks me out at work just to talk. My problem is, currently were flirty and stuff on the down low and she seems to be taking it up a notch blowing me kisses, trying to meet up, touching me etc. However all I really do in return is the usual joke and mock her because I'm too nervous to say or ask anything personal or serious. I want to let her know that I'm interested but don't know how to respond to all her signals without choking up.

Appreciate responses
