Breathing practice is a way of paying attention to the rise and fall of discomfort within you. We think about so many things, whether it's exercise, eating a vegetable that you don't like or going to class - all of the escapes that we give ourselves. So I think a lot of people will get benefit from learning how to tolerate and not give into a rising sense of discomfort from within. If you want to continue working on those feelings, those emotions and things like that, and you can return to this practice to let those feelings come up.
