I can't stop crying

Tomorrow my best friend is moving into her college dorm, and on Friday my other best friend is moving into his. I'm not leaving for another week and, unlike my two best friends who are going to school in state, and will be an hour away from home max, I'm going across the country. I'm an absolute mess. The three of us are so close I can't imagine life without them. Which sounds dramatic but I can't think of any other way to explain it. I can't stop crying bc I'm so scared we will drift apart and I love them both so much. I know approximately one person at the school I am going to. I haven't been this depressed since I moved schools my sophomore year of high school. I keep crying and I don't have any motivation to do anything. It's so bad. I know that once I'm in college I'll have fun and that's what everyone keeps telling me. But right now I can't handle it. I'm such a mess.
