Refer to the research of Rimé et al, _Social Sharing of Emotion (see references) who have found people talk about troubling topics like emotions a lot. Some suggest this is an indicator that talking will clarify your understanding.
I've heard that keeping a journal can also be helpful for sorting out and expanding on emotions. This is assuredly related. More often it's framed from the perspective of getting things out rather than working them out.
This could be useful research to read.
