My head is killing me.... (Relationships)

So, let's just get the quick stuff down here. I met a girl during a speed dating event. I got her number, and I thought I'd see her in person... Wrong. We talk daily, not long. She'll text me good morning, and send me the occasional selfie. However, I'll send her a text, and wait all day to hear from her. She told me she's busy and has work, and such. It's getting to me, BADLY. She's shown interest, and knows I like her, but at the same time, it's driving me insane. My anxiety has been RAGING, and I can't stand it. Is she playing hard to get? (She told me she's been hurt very badly in her past, so I would understand here) I've wanted her since I first caught her laugh as her emotional support dog pulled her into the room for the event. She's physically beautiful, but I truly feel like there is something inside that is making me want to leave work right now, drive to her, and just tell her, and hug her... DAMMIT!
