Do you have PMDD??

Stephanie
I've always had bad periods and was diagnosed at a 9 with PCOS due to irregular periods. I'm 25 now and my periods are so much worse than before and I keep getting new and horrible symptoms ever 6 months or so. 
I now have vertigo, dizzy spells, high and low blood pressure, tremors, nausea, GERD, muscle weakness, and insomnia, just to name a few. In the end, it's extremely debilitating to the point where I can hardly get out of bed for a few days.
I heard that Premenstural Dysphoric Disorder, if left undiagnosed, can continue to get worse (symptom-wise).
I never thought that a lot of my symptoms could be related to my premenstural and would like to know if anyone who is diagnosed with PMDD could give me some insight.
Thank you.
