I also have PMDD. My gynecologist suggested I could take birth control continuously skipping periods and it would possibly help. I think if I found the right birth control it could, I am super sensitive and the birth control I have tried in the past made me feel worse because I get symptoms during the month, so I have been too scared to try it again. From my understanding of talking to others with PMDD everyone responds differently to different treatments. Reddit also has a PMDD subreddit that you might find helpful. I find it quite supportive. This website also has some useful info: IAPMD. Hope you find something that helps!
