The Problem With Discourse Particles in Conlangs

There's a lot of things here where people are going to want to, um, search for things. I think the problem that I have with these, especially when adding them to a conlang, is rather the extent or making it so they don't just cover the same semantic space as like an English anyway. And then the other problem I have is saying it in a different way because it do kind of mean nothing on their own. It's kind of hard for me to come up with new ways that aren't just copying other languages I know.
