This emotional state is one of a complete range of emotions; mostly hurt and anger.
It has many stages, and the first is usually shock or denial. After this, and the words of your once beloved have sunken in, it will feel as if your heart is literally being ripped out. This is because you will experience pain such as a tightening in the chest, stabbing pains in the chest, very heavy breathing, and an increased heart rate. You may diagnose yourself with a panic attack, but this is usually not the case. For some period of time (usually a few days to a week) you will feel as if you have an extreme case of an anxiety, and you may not like the thought of eating, for every time you do, it seems that the food will come right back up. Lack of sleep is very common, and you may be convinced that you are suffering from insomnia. Tears and crying also play a major role, but after about a day you will find that you no longer have any more tears to cry.
You will experience a feeling of complete loss of hope. You may feel angry with your friends/family because everyone keeps telling you it will get better, or they may cut down or insult your ex and tell you that you are better off now. You feel as if no one in the world at that moment can comprehend the amount of pain and anguish you are in; you do not want to hear that you will feel better soon, or move on. It doesn't seem that way at all. You will dwell on all the memories you once had and wallow in the mere fact that they are over. All future plans, little or small, are now gone. Any dreams or things that you had wished to experience with that person is gone, and it is almost impossible to accept this. It is almost imposibble to accept that you won't get to hang out, kiss, cuddle, joke around with, and plainly-- be with
the person that has both made you feel such incredible happiness, and despair. You may look through e-mails, text messages, notes, or voicemails that they had previously sent you, and the memories flood back and you find despair once more.
When heartbroken, you will still experience bits of happiness, however, your moods and emotions will be on a roller coaster. To be heartbroken is one of the worst and most common experiences that people will go through.
He said we had to talk; the only thing that could describe how I'm feeling after we had, is that I am completely and utterly heartbroken.
