Friends can come and go, and feelings come and go for friends. I used to love my best friend. She lives 1000 miles away and is married now. Shes a great friend but we drifted a bit, and that's okay. We're both off doing our own things and living our own lives.
You can dwell on it for a while, but don't dwell too long, that's when it becomes unhealthy. Just find something to stay occupied, be it work, school, hobbies, something. ANYTHING is better than constantly thinking about it.
