I also wish it was easy to get over an ex. It is truly hard to completely get over someone you loved.
Patience. I know you dont want to hear that, but in due time, you'll be happily saying you are over the person and feel accomplished as opposed to how you feel now. I'm not gonna tell you keep your mind off her, cuz it is basically impossible. In some cases, moving on does help people to get over someone. Maybe you should go out and meet new people?
