This advice from an article on this website has been extremely helpful to me in dealing with heartbreak.

We all want closure. In looking for this type of closure, we are often giving away our power. We’re saying, “I cannot move past this experience until…”

The outside world cannot take care of our feelings. Only we’re able to do that internally. Release the need for outside mediation or validation.

Assert that we can move forward regardless of what is happening in the outside world.

Remind yourself that anger hurts you more than the other person who upset you. What can you do about this? Visualize it melting away. This is an act of kindness to yourself.

Also remind yourself of how this person was not perfect and potentially unhealthy for you or prevented you from moving in a forward direction in your life. Think of the quote, “It’s easier to let go of a human than a hero.”

We can all get through this! I can say with absolute certainty that we won’t feel this way forever. The only constant in life is change and it would be impossible to remain in this state of mind. Amazing, fulfilling things are ahead of us!
