I have seen that grief can be very different for different people. While the range of emotions experienced is similar, the way we deal with those emotions isn't, necessarily.
For sure, the funeral industry seems intensely cynical to me and I don't think it is HELPING people mourn.
But there is a discomfort that surrounds grief. It makes even the most well-intentioned people unsure of what to say. And so many of the freshly bereaved end up feeling even more alone.
The people we most love do become a physical part of us, ingrained in our synapses, in the pathways where memories are created.
