I am not a native English speaker, but I consider myself to have a solid knowledge of the language, obtained through years of reading foreign literature. I am also an amateur writer, who's now starting to write short stories in English, to publish on sci-fi and horror magazines.
I am asking this question here because I am willing to use the 'lest' contraction in a sentence. The way I constructed the sentence looks right to me, but I can't feel sure if I indeed used it correctly. Several questions about the usage of 'lest' were already asked, but since I do not possess a deep understanding of the English language (self-learner here), I am still confused about if I can or can't use it.
The sentence in question is the following:
I definitely wasn't that much popular. Very few people even talked to me, lest be my friends. But, at least, even fewer dared to bother me.
In this sentence, I tried to use 'lest' to give a sense of 'let alone be my friends'. I chose 'lest' instead because it sounded better.
Examples of similar questions are:
Again, I am not a native speaker, and a self-learner, so pardon me if the question is somewhat already answered on any of these links.
Thanks in advance!
