Pmdd support dublin

I have been suffering with what I am certain is PMDD, for nearly 10 years, I suffer with my mental health in general but my whole life revolves around my period coming, 10 days before my period everything changes like a switch goes off and everything is turned upside down. I am constantly rebuilding my life and good habits back up every month once my period leaves. I need help but I don't know where to start. Side note I was on the pill for 5 years before it started and oh my god did the pill exacerbate the symptoms. So I can't take the pill.

Any advice will be much appreciated.
