Here’s an analogy I’ve made to the grief of losing a spouse and the inability of those who know no such loss to understand why we are the way we are: Unless you’re standing in the middle of the swamp, you have only a vague idea of the monsters that live there – no-one outside of the widow’s or widower’s skin can understand how the loss impacts them personally. Even those standing in the swamp dealing with the monsters are dealing with THEIR monsters. Everyone’s experience is different.
I guess the point is that, though people will tell you that they know how you feel, or they understand, they really can’t. Widow(er) to widow(er) has the best chance of understanding; however, everyone came to where they are by different paths, each which imprints differences – some small, some vast – in the experience.
For those looking to comfort a widow or widower, you really need to understand this. Telling someone you understand where they’re at really doesn’t give comfort. Just talk to them. Be aware of their pain, but don’t avoid them because of it. And to those widows and widowers who take offense at the usual platitudes, keep in mind that the goal of the person is rarely to be dismissive. They really don’t understand, and only want to give comfort.
