Hormone changes after birth control

Hi! I just came of birth control a little over a week ago (after almost 20 years) and I thought I’d be relieved and excited but honestly, my mind and body aren’t responding well. I’m so so so sad and emotional and I know it’s chemical and will (hopefully) pass but I’m looking for advice. Did anyone else experience this? Any advice? I already follow a pretty strict diet for PCOS but my team at work are starting to notice (I’m typically a very bubbly person) and I want to try to get back to “me” as soon as possible. Thoughts?
