Four years is okay to feel so lost without someone! Your mind is the one thing that keeps wandering back to how bad you feel, and you need to keep it occupied while you grieve your relationship. So over time, yes it will get better, so in the meantime, keep the mind busy. Do puzzles, read books, watch movies that will cheer you up, call up an old friend that you haven't talked to in a long time so that you can catch up on news that will engage in a long chat. Try something new that you haven't done before. If you haven't golf, go to a driving range and rent a couple of clubs and see how you like it.
After ending my last long-term relationship, I read book after book to let my mind escape to something else. Eventually I went from reading to writing my own book. Gathering all my thoughts and keeping busy writing was therapeutic and after a long time, I could look back and read what I had felt that whole time, and I could tell I had done a lot of healing.
