This was touching. This is probably the single most important yet unanswered question that exists in the world regarding feelings of pain and suffering. You always ask yourself how long it will take until you are able to breath.
Take the death of my father and sister, when I was just 8 years old. I have still not “healed” even 24 years later. In this circumstance thing only thing that you can do is to understand that the pain never really goes away. The loss stays forever in you heart, you are just able, one day, to breath. You’ll still have moments of unrelenting sorrow and grief, but you can move forward in the living.
So I guess the better question is; in some circumstances, does one ever really heal?
