Such a tough topic to write about.
Good Eggs meanders quite a bit through time to hit a wealth of different subjects Potts has confronted in her life, but I wouldn't compare it to Persepolis or Fun Home (which have very concrete themes & high stakes conflicts). It IS an excellent visual representation of depression, or "The Voice": text that intrudes on her other activities to remind her that she's a worthless loser--but unfortunately, that's not the subject of the book.
