HeIsHere asked, "How is that scripture connected to DID? What do you base it on?"
My response is a work in progress. I'm seeking to learn more:
(Proverbs 27:17) As iron sharpens iron, so one person sharpens another.
As I see it, the spiritual world is usually not part of the average scientist's world view. MPD/DID are scientific terms used to describe a phenomenon observed by the medical community. Science, as commonly practiced, describes material interactions and does not have the tool set to describe anything of a spiritual nature. Thus, 'diagnosing' someone with 'MPD/DID' is simply identifying a particular human affliction in materialistic terms.
So, what is 'the heart' according to Scripture? You can search and you will find many definitions. It seems to me that we must first understand what the 'heart' is before we can consider what a 'broken heart is'. Jeremiah gives us a clue when he says:
(Jeremiah 17:10) “I, the LORD, search the heart, I test the mind, to give to each person according to his ways, according to the results of his deeds.
Jehovah says He searches the 'heart and tests the mind'. To me that indicates that either the mind is found in the heart or it is the heart. In common usage, the term 'a broken heart' usually has the connotation of a deeply disappointing event that hurts someone or 'breaks their heart'. It is usually not considered a life threatening event but rather something they will 'get over'. Thus we have the saying, "Time heals a broken heart." When Jesus Christ stated that he came to 'heal the broken hearted', this was not the human condition he was referring to. He had in mind a much more serious and potentially deadly condition which no amount of time could ever heal.
When Jehovah would discover the true essence of person, He searches the heart to test the mind. Thus, according to Jeremiah, our heart, however you care to speculate about what it is, contains our true identity. If a person has a broken heart, that can only mean that their identity is fractured; e.g. they have multiple identities. What does that mean?
Someone experiencing a broken heart is not a unity; is not 1 person. Typically, they have managed to survive traumatic events by splitting or breaking off a portion of themselves; a portion of their heart; a portion of their identity, that will endure the abuse while enabling the person to survive. I think that God, who knows all, provided this mechanism for the survival of His children who endure horrific abuse. My conclusion is that Jesus Christ is deeply interested in 'binding up the broken hearted', restoring His lost sheep to Unity, to a single identity.
(Isaiah 61:1) "The Spirit of the Lord GOD is upon me, Because the LORD anointed me To bring good news to the humble; He has sent me to bind up the brokenhearted, To proclaim release to captives And freedom to prisoners;
