Transitioning from Old Self to New Self

This may be a strange question. As I’m learning, and hopefully engaging, more and more of my authentic self in my day-to-day, will there be times of “missing” the old way of habits and feelings? There are days I feel “left out” of things, even though I feel balanced and know all is well. I’m wondering if I’m not paying attention to something, in denial, and those kinds of things.
Thank you.
