military gf help!

hey guys so I’m 17 and my boyfriend is going into the military. We’ve been together for 9 months and we both made the decision to stay together. We love each other a lot and see a future together. He’ll be in boot camp for 5 months and our only communication will be through letters. I’m so scared but he’s worth it. Just looking for support and wanted to see if anyone’s been in my position or similar?
