College is stressful.

I looked at the Grinnell link out of curiosity. Not offered every year, but they have a Composition Seminar intended for serious composition students, and they have a course called Introduction to Composition. And they teach Aural Skills, Harmony, Counterpoint etc. http://catalog.grinnell.edu/content.php?catoid=14&navoid=3141 I think Grinnell could be a great option for the OP. They actually have two composers on faculty - not as adjuncts. https://www.grinnell.edu/users/rommer and https://www.grinnell.edu/users/mcintyr2
