Boyfriend left for a two week vacation?

my boyfriend left for a two week vacation to ireland and before he left we got in a fight and we had a very sad goodbye. He hid a pair of his pajamas in his yard so i could wear them and feel closer to him while i was gone, so today after he left i went and picked them up and there was a note with them that said "Im sorry for everything :( I love you so much" He wont have internet/texting/ and might not even be able to call because of ridiculous bills. Anyways, I feel so lost and i dont even know what to do, i feel terrible and i miss him so much already and he just left today.. Were both 17. What should i do?
