Dang it, I don't know!
Umm -- how's this. All venting is processing; not all processing is venting. ("Venting" is a subset of the group "processing."
) So processing an experience (also called "integrating") might be: talk therapy, making art, venting, confrontation, re-imagining, posting on a message board, stewing, meditation, or even just plain old noticing something for a moment. Many tools for many situations.
We might gain from a forgiveness ceremony, rather than venting
So the sequential thing I referred to, is that forgiveness cannot happen until after an experience is "processed." For you, that processing may happen quite quickly and internally, esp. as you are negatively sensitive to venting and it is not effective for you as a processing tool. Then you like to move to forgiveness. I guess when I said "forgiveness follows
processing," I just wanted to point out that forgiveness, however necessary, is not a substitute
for processing/integrating experience. And for many, the path to forgiveness is a little longer, or includes venting about an incident, or even spirals (venting/forgiveness/more venting/more forgiveness, etc).
Dear lord I hope this makes sense. It seems perfectly simple in my head.
