Breakups are horrible. Is this your first serious breakup?
I don't think there are any magical words to say to you to make you suddenly get over her and feel happy. What you need to do is surround yourself with people that care about you - friends, family, co-workers if there are any. Get yourself busy - work, activities, hobbies, movies, tv shows, gaming, etc (although it sounds like you got this part covered already which is great). Whatever to keep your mind busy and not dwell in the negativity and depression that comes from breakups.
Always know that feeling like shit is common and don't be too hard on yourself, some people can move on easily and some don't, it's very subjective and tied to how deep was your connection.
I was a real mess during my first breakup and I couldn't get her out of my head for a real long time, probably up to a year as well. As cliche as it is, time really does heal it all. I know you may not believe it but don't give up hope, and try focusing on your current partner! Don't compare her to your ex, every person is different and unique in his own way.
Good luck mate!
