I realize this is very old, but I’ll reply anyway!
I had the exact same problem – horrible, awful PMS. The anxiety was crippling and I thought I was losing my mind. It took a while to make the connection to the birth control pills, since I had been on them for about five years at that point. I tried a few different brands but nothing helped, so my G.P. referred me to an OBGyn. He suggested taking daily Vitamin B6 (100mg) supplements, since oral contraceptives can cause a deficiency.
I did some Googling at the time and found conflicting reports, but figured it was worth a try. It helped, oh my god did it help. Along with regular yoga practice and a mostly good diet, I was so much better. I went off it for a bit, because I was lazy and feeling much better(!), and within a couple of months found I was having the same terrible symptoms. (Which are not good for any relationship…)
