A time will come in all our lives, although I pray for your sake that it does not and I'm sure that you do as well, where we will be tested. And no matter how stable we have been throughout our whole life, no matter how strong we feel that we have been in the past, it will try to break us. To an extent it will succeed. If there were an analogy it would be a person against a steam roller. Regardless, of how tough and sturdy somebody stands in front of this beast, It wont even feel a bump as it rolls over and makes tomato paste out of you.
Emotional Constipation is the term that I have conceived, and maybe others have too in the past, that mainly refers to the fact of how one is driven to a point beyond breaking. Different for everyone, experience of contextual unimaginable hurt, be it emotional or physical, that the person cannot express themselves. They cannot vent. The person is there in a vacuum, on hold, a void of sorts where the person's only pass time is contemplation. The optimism waivers and the darkness ensues. Yet, it is impossible to vent.
Mind you this is not Emotional Numbness for better or worse if one was numb then the benefit there lies that the person does not feel anything. However, with the former state one feels everything and deeply so, yet those feelings cannot be expressed. One wants to weep but cannot, one wants to cry out loud but cannot.
Such is the state of Emotional Constipation. May Allah protect each and all of us from this and give us the strength and courage to wade through this swamp.
