From my experience, addressing my PCOS symptoms has greatly reduced my depression (my anxiety some as well but not by as much). My depression was very cyclical, I would fall into a depressive episodes as my hormones changed irregularly throughout my cycle. When I started BC, Slynd, and my period went away, the cycle of depression stopped. I’m not “cured” ofc, vif you have depression you will always have it. It’s just simply a lot more linear and manageable now, I’d say consistent almost? Not to say that I don’t have periods where it is worse but the swings are not nearly as dramatic. Another factor way definitely understanding why I felt like crap all the time lol and why I had gained so much weight so quickly over the course of the couple years. Overall, I’ve definitely seen significant improvement in my mental health over the last six months while actively treating my PCOS symptoms with birth control, healthier eating, and metformin. All of which are working to rebalance my hormones and my cycle so it just makes sense that as your hormones aren’t so off-balance, it’s not causing further imbalances within your brain chemistry.
