My girlfriend won't text me back what should i do?

(My girl is a lez, i'm bi) We talked for a while now. It started on skout. Then we talked on kik (for iphone android ect.) then she gave me her number. We talked pretty good for a lil while then wednesday i texted her in the morning. She didn't reply til that evening saying her mom had her phone all day. (She's also in school) Can't say she's lying (she's in texas i'm in missouri) so i texted her back. No reply. Waited til the next day. Texted her again no reply. So when that happens i kinda get anxious and start send a lot of messages. I can't stand to be ignored. Its now monday and i still have not heard from her. Should i keep sending message or keep it cool and wait? I wanna wait but then i start thinking negative-shes ignoring you or something like that and it makes me wanna send more mesages. Then i start to think positive - maybe she's just busy (she's done something like this before) and it kinda calms me down. I also tried messaging her on kik. Sent quite a few messges there too. The first few she actually read them! But she didn't reply.It hurts bad! The others i don't know i deleted the app to keep me from messaging her. I know she's not mad because the last few times we talked was beautiful. Showed no signs of being mad. I NEED Help.

Added (1). Some people say to talk to other people but i don't wanna do that cause i feel like I'm cheating. But will keep her off my mind…

You ignore her until she texts you multiple times.
