What should I do with this girl? communication got cut off?

Anonymous
I started talking to this chick and started to catch feelings for her. We were talking for almost 2 weeks and we were going to meet up again in 2 days then my communication got cut off from her. Her username name changed and Snapchat said she doesn’t exist? Yet I can still text on our chat without a notification of any sort.

We were texting every day, sending pictures, and were into each other. It was all of a sudden this happened and I don’t have her phone number. I feel dumb I didn’t ask for her number now but what do I do? It’s been a day already and should I be worried?
