The Unholy Trifecta: ADHDxPCOSxPMDD

Who else has collected them all and is dealing with ADHDxPCOSxPMDD? I'm 37 and I have lean PCOS, so extra fun! I do have insulin resistance though and just got my copper IUD out for the PMDD. On day 5 of my period right now and mood and sleep are still absolute shit. What are we doing to manage this? HOW ARE WE COPING?
