My character is alone talking to herself, saying the things she wished she had said but didn't have the courage to. I do it all the time myself, only it isn't a lack of courage so much as I think of the things I wished I'd have said that I didn't say at the time. I know this exercise in magical thinking has sone therapeutic value. In grief counseling when the person says, "if only X had happened, if only I was there sooner, if only ..." it's part of the coping mechanism when one is grieving. So my character gets interrupted in her mental exercise and I had written: Seeing a lumpsucker in my trap ended the mental catharsis. But the critique group thought catharsis was the wrong word and I'm having trouble coming up with another one that works.
