I'm not diagnosed but I believe my symptoms match the description. There have been so many months where in the day or two before my period, I have come so close to driving my car into a wall, taking an overdose of whats available, the urges to self harm become so overwhelming. It feels like an entity takes over my body, and I feel totally powerless. I spend the days in floods of tears in my car and then the minute I get my period, it begins to lift and I go back to my usual low level/ high functioning depressive state. Its been a factor in sabotaging potential relationships tbh which is depressing in itself!
