Well, first off sitting with your feelings can be one of the scariest things you ever do.
You may perceive it to be way harder said than done. And sometimes this isn't just a perception but has been based on actual experiences in your life.
Maybe there were times in your life when you experienced a difficult situation, but you did not get the support you needed.
You may have been told to "suck it up, stop being so emotional, you are fine, it's not a big deal, etc."
Maybe you took on these messages as truth and internalized that you are too much for others or that your emotions are bad.
Or even deeper, YOU are bad for having emotions & YOU are unworthy of support and love from others.
This may be the cause of your so called "emotional wound".
So as an adult, when you experience challenging situations, you stuff any difficult feelings down and avoid them at all costs.
& if you are a parent, you teach your children to do the same.
