LDR- Help 😩

Okay, so I have been in an LDR with my boyfriend for 9 months now. I love him with all my heart, truly. He actually recently just visited me for a month and it was such a special time. He left back for Germany 11 days ago, and I've been missing him like CRAZY. And he is about to start his internship, which lasts 1 year. Then he plans to come to America, which of course is exciting. However, he is on this 5 day training, with barely any internet and so we wont talk much :/ Which is disappointing. And he is so sweet and keeps telling me "I miss you" and "I love you" whenever he finds internet. But its not that Im worried about. Its the fact he starts work soon, like a real 8 hour 5 days a week job. And with the time differences and his internship and me already missing him like crazy....idk :( Im scared and worried.
