Well, there are a couple of methods that can be quite effective if you try them. First, you might want to try to get some physical exercise.
Yes, I mean physical exercise. You probably feel like it is the end of the world. Perhaps, you don't even feel like moving. You might not even feel like getting out of bed. You just want to lie in your bed.
Yet, the more you lie on your bed, the more depressed you will feel. Exercise will produce endorphins in your body which will make you feel better instantly. You can exercise alone. Or you can ask a few friends to join you.
You can choose sports like tennis for example. You can hit the ball hard if you want to vent your frustration. Of course, take care not to injure yourself or others.
The next thing you can do is to find someone you can trust to listen to you. That's assuming that you are comfortable about talking to someone. In fact, if you are not comfortable talking to people face to face, you can always try talking to a pet if you have one.
It may or may not work for you but you may want to try it out. The act of just saying it out can relieve your emotional tension.
Also, if you feel like crying, just cry it out. You don't have to do it in front of anyone. You can just do it in the privacy of your own room. Nobody will know it. Crying can be a very healthy way to relieve your emotional tension.
It can take a period of time before you start to feel better. Whether you still wish to get back together with your ex or not, getting yourself into a better emotional state should always be a priority.
With a more positive emotional state, you will have a clearer mind which will in turn allow you to make better decision.
