Oh I completely understand about PMDD as I'm experiencing the same thing. This last cycle was terrible. I always feel really on edge a few days before it starts, like I could explode. I couldn't sleep and I was full of rage. I cried for like 4 hrs straight. It's hard to understand what's going on with your emotions. It's hard for people who don't have this issue to understand. I wish I knew this answer, but I'm still working in that myself. You can message me anytime if you want to talk. It definitely helps talking to people who understand. Hang in there!
