I am sorry you're hurting so. :( The only answer is "something - anything."
Do something you love. Do something important to you. Look over your bucket list and get to work. Read a good book. Binge-watch a good TV show. Go see a movie. Do something.

Write... listen to love songs. Cry. Then decide that everything is not meant to be. People come into your life for a reason but it doesn't mean that they are coming to your life to be a permanent existence. Dust yourself off and remember the good times and face the fact that it was a chapter in your life that's done and it's time to start writing the next one.
