I know it sounds cliche, but time WILL heal.
My best advice, having gone through two terrible break -ups..allow yourself ONE day to cry and feel bad...get it out. After that...you have to try with every ounce of yourself to keep busy...I read A LOT of self help forums, advice columns, chatted with strangers, friends, etc...
Get out of the house - go for a walk, go shopping, take a solo trip (camping helped me)
Delete the contact information! This is IMPORTANT and will help, trust me!! (as hard as it is, TAKE THE POWER BACK)
Put your effort into making YOURSELF better NOT getting them back
Make a list of Pros and cons about the relationship

you can do it if you want to...

it will get better and you WILL meet someone else.
