Or, even better ‘I didn’t sleep that night’ which would leave it open for continuation.
However, this is very eloquently written, especially the second paragraph. I like your spacing as well, keeping the last three lines entirely separate adds weight to their content.
I’m still trying to work out the story line in my head. The narrator seems to be quite a sad story, watching the joy from a distance but not joining in. Nicely written. Abby x
