Hi there. I'm new here. Hormones totally affect my moods. A decades long pattern (I'm 48) is that when the PMS time hits my mood plummets such that I get suicidally depressed, even when nothing else bad is going on. So for years I have been on the contraceptive pill which stops my ovulation and thus PMS. It's helped me so well (I have multiple complex mental illnesses). I'm not sexually active so it's simply to manage my hormones. Just a thought.
