SUBREDDIT: r/relationships
TITLE: My [14M] girlfriend [15F] has been at an away camp for multiple weeks and will be away 1-2 more, and she hasn't contacted me. At all.
POST: Hello Reddit! 

(Pre-note: Keep in mind, my SO's parents are very notably restrictive and protective - I don't know why she hasn't contacted me, and it may be due to her parents. If need be, I'll be known as Cole and she'll be Tiffany. This thread is marked as Dating because it's unclear what's happening between us to me as of right now.)

My girlfriend is currently at an away camp type thing - it's an advanced studies program (Duke TIP) and she hasn't contacted me for several weeks. The reasons I can think of why she hasn't contacted me:

-her parents 
-she doesn't want to talk to me anymore (worst case) 
-she's not allowed to use her phone (program rules) 

I'm starting to get really scared that she doesn't want to talk to me, as she assured me she would be able to contact me at least once a week, however it has now been three weeks with no interaction and I'm worried. 

Relationships, what do you think the problem may be? What do you think I should do when she gets back? What is life? What would be an easy date (as in, relaxed) that I can take her on a few days after she gets back where we can cuddle? <3
TL;DR: 
I haven't talked to my girlfriend in forever because she's at an away camp and I'm scared to holy hell that I'll never see her again. I'm asking you cool guys & gals for advice.
