Ok so this happened to me, only more severe than what you described. I’m bipolar so I just brushed it off as yet another episode, that stemmed (at least partly) from getting my period. I have PCOS and a hormonal IUD, and my periods are not regular. I was actually hospitalized for eleven days. They had to double my antidepressants.
What I’d suggest is DEFINITELY make sure you’re getting enough starchy vegetables. They play a role in serotonin production. I make sure to get 2-3 servings a day.
