Last Day

My boyfriend and I are a long distance couple. He is from Ohio. I'm in Texas. He is also a Marine stationed in NC. This week has been the first time I've seen him in two years. I leave for home tomorrow. And I'm so not ready. I'm extremely emotional (my brother got diagnosed with neuroendocrine cancer that's the only reason I came to Ohio. My boyfriend took leave to visit family it just happened to work out.) And I'm not prepared to leave him again. What are yalls best coping mechanisms.
