I've just been diagnosed with PMDD too, this is the first cycle since the diagnosis and I am monitoring myself very carefully. The anxiety was off the charts yesterday, I couldnt believe it, and I was so disappointed. I have been able to control my anxiety very very well so it felt like a huge step backwards when it hit me so hard. I dont have an appointment to get it sorted until december so I upped my antidepressant until they give me something else to help with it. Its not been so bad today, but I am still recovering from yesterday. I forgot how much extremely high anxiety takes it out of you.
