Unfortunately, the heart doesn’t know this word “fast”. Broken hearts do heal. Techniques which I have found to assist me in ‘moving on’ are:
-any activity which cause one to listen to how they feel: journaling, fluthering, talking one on one with a trusted friend or family member (preferably female).
-exercise, especially exercises which encourage self-talk (running, walking, hiking) are very helpful, because the exercise drains emotional energy, allowing clarity of mind.
-Set new goals for yourself/work towards long standing long term ones. My long term goals pulled me out of navel-gazing because they weren’t dependent upon the S.O. who no longer was a part of my life.
-Check progress based on the cycle of grief link
progress is encouraging, and gives a sense of momentum, which generates feelings of “I am going to get through this” and “things will get better”
Hope this helps!
