Breaking up with your ex is really painful and could give you nightmares for weeks and months. In the first couple of days after break up you can feel numb and unable to perform your normal duties. But time will heal all of these things. There are plenty of fish out there and you might learn a lot of things about the break up.
The first thing you need to do is to let your feelings out. Talk to a close buddy of yours and let your feeling out to him/her. You might feel very awkward at first but letting your feelings out can make you feel good afterwards. It's really important you talk about and not let it fester in your mind. The more you let your feelings out, the more free you feel.
Instead of feeling miserable about the relationship, use it to your advantage. Try to make the feeling of sadness as a motivator to pick yourself up and get moving. Try to have fun and really enjoy life. After a while you will notice that life is not so bad after all and your problems will become trivial. There are plenty of good things in life and there's no point in moping about your problem. The best revenge on your ex is to be really happy with yourself.
Another good way to get rid of your heartache is to date as many people you can. You notice after a while that there are plenty of people you want to meet and may find them even better than your ex.
