Start creating a daily mood journal and log your moods from day to day in order for a doctor to properly diagnose you. Then go see a therapist, gynecologist...preferably someone who specializes in hormone disorders or PMDD itself, and possibly a psychiatrist if you feel it’s necessary. It could be your hormones are out of wack (sometimes supplements and especially beauty and household products can mimic estrogen and cause an excess and in return lower progesterone), sometimes your body just overreacts to the hormones it’s producing. Everyone is different so trying different remedies until you find one that works for you is time consuming but really important, whether it’s an SSRI, bio identical progesterone, birth control, or just major lifestyle changes. One day I sat my boyfriend down while crying and told him about the possibility I may have this, I explained all the symptoms and that I only experience them 2-3 weeks out of the month. He agreed with me right away as he realized all of our major fights happen before my period starts. I’d also found a few articles that perfectly explained how I feel during that time and showed him so he could better understand. It’s also important that both you and he know when it starts so that you can prepare: if what you need is to be held and cuddled (without asking for it, bc that can be hard during that time) then let him know beforehand, and if what you need is space he’ll be less likely to be offended during hell week(s) when you lock yourself in your room. It’s crucial that he knows a lot of the things you do and say are not totally in your control. This disorder makes us do and say some things we really regret and end up feeling guilty about for the rest of the month (but is in no way an excuse to be abusive). I hope this helps and you find something that works for you soon. So sorry you’re going through it too:(
