My girlfriend just left for basic training

Hey, I’ve never posted on Reddit before but I just feel really alone right now. My partner just left for Air Force basic training and we’ve been dating for over a year now and we’ve spent almost every day together. We lived together the last few months and right now I just feel so alone, I’m so proud of her but I’m so sad too. I feel so empty and uncomfortable without her. I’m just so sad I can’t talk to her right now. I don’t know how I’m going to handle not being able to talk to her for 7.5 weeks. She’s my best friend and my favorite person, I’m just so sad it’s so quiet at home now. Does anyone have any tips of how to make things easier? I have to go back to work tomorrow and I don’t know how I’m going to hold myself together.
