There are some common ideas about what causes PMDD or Premenstrual Dysphoric Disorder. The article reviews these ideas and some things to try that may or may not work for you.

“When it’s bad, I can go between three to five days without showering, leaving my room or talking to anyone.” PMDD pushes some folks to isolate and that can cause more depression. It is difficult to match what a person dealing with PMDD needs and what others have to offer in a way to comfort.
Please reach out for support maybe by talking to a doctor, a counselor or a trusted friend. Also this organization has resources and information that might just make you fee a little less alone. The International Association for Premenstrual Disorders.
