Girlfriend is gone till 30th july, im leaving 24th july, i will be gone till dec. 20th, WHAT SHOULD I GET HER?

So my girlfriend left on june 28th for an explorica group that tours around europe and she is going to be gone untill the 30th of july. I am going to be leaving on the 24th of july to go to Fort McCoy's Challange Academy (boot camp pretty much). i am having a hard time with her not around because i lived at her house and i was used to being by her side every minute of the day, now i cant see her until DECEMBER :'( So i was just wondering, can anyone help me out with something that i can get her or do for her for when she gets back???
