Yep check stickys on the relationship board. For a start you need to:
1) Put all reminders in a box away out of sight
2) Start no contact - maybe you want to let the ex know or not, up to you. "I think its best we don't speak again."
3) Get some plans - something to look foward to. Maybe a music festival, cinema, travelling, a holiday
4) Ever wanted to do something? Nows the chance, go to the gym and get ultra healthy and get a great body. Excercise is a great stress reliever and makes you look good to
5) Don't mope around at home, get out and about with friends and family
6) A breakup isn't the end of your life, life goes on. Ask other people what they did and about their ex's, maybe they can help you with your recovery
