can’t tell if this is a joke about how the patriarchy subdues women with antidepressants, or about how the patriarchy has created the conditions that caused her depression?

In medical terms that concept is called “social determinants of health”. Very real stuff that’s been well-studied and taught in medical schools for many years now.

I hope that one day in the future, even if its a few years away, you’ll write in your diary that the reason for your not needing anti-depressants anymore is “having healed from the patriarchy”.
