GIRLS - She hasn't replied in ONE HOUR, am I doomed or what?

Met this girl, hit it off, lots in common and got her number. She seemed pretty into it. I texted her at 9:45PM tonight, and it's been a bit over an hour and she hasn't replied. I'm thinking "alright maybe she's busy or sleeping or something" but I have anxiety so I'm freaking out now... what do you think?
