It would be a lie to say that everything will get better soon, but it will get better. Use the time you have now to create a new fire from the ashes of your past relationship. Alcohol... whilst doing a fantastic job at masking the pain for a time only makes things worse /b/ro, so don't go down that route either.
I know it's a cliche, but go out... join a gym. Indulge yourself in a hobby you haven't had much time for, spend the next months in forging a new path for yourself.
Listen to great music too, The Smiths is great for break up. Try and look for some experimental stuff outside of your comfort zone, take solace in discovery.

And go out, walk the countryside. Keep walking man.
