Interning while teaching

I'm currently enrolled in an administrative leadership program. While this is enjoyable, the internship portion of this is not. How many people have to do internships while working full time? I'm sure there are lots, but it still doesn't make a lot of sense to me. I guess, however, in my case, the internship while working is a good idea. I just wish I had some extra time to get things done. Or that my brain didn't feel like it was about to explode all the time.
