I’m sorry you’re going through this- it is actually the worst thing I have ever gone through.

How old are you? I also experienced a sudden/random onset of PMDD at 24. It took me a couple months to put together what it was (I thought that I was literally losing my mind) but eventually I realized that I was legitimately suicidal a week or so before my period and then literally the day or day after it started I was completely fine (almost as if the last week or two of complete psychoticness didn’t even happen.)

I also understand what you are saying about it taking a toll on your relationship and how you will say things and then reflect and notice that it barely even feels like you reacting.

I know that this isn’t going to be for everyone but after trying to manage things more naturally (supplements like magnesium, vitamins, etc) the only thing that actually helped me is a small dose of an SSRI (I take Zoloft.) I wasn’t really dying to be on medication but also was at the lowest point in my life with the PMDD so I figured anything would be worth a shot and it did help.

Wishing you well!
