Struggling with PMDD: How to Get Through the Day?

I have no idea. I felt less emotionally stable than a toddler who skipped their naps yesterday. Today is only a tiny bit better. My tolerance is just gone. I tried medication but it's not working as well as I hoped. I stopped taking it and was trying to take it only during the luteal phase of my cycle but then whenever I start it again, I feel weird

It must be going around. If I weren't medicated I would have absolutely had a PMDD induced emotional breakdown today, it sucks
