I Go Crazy a Week Before My Cycle

And I do mean crazy. I get anxious, angry, depressed until I get one good cry out for the day. This continues until my cycle starts and then I'm fine. My fiance just ignores me, but i find this to be irritating and my wedding day is coming a week before my cycle. Do anyone have any suggestions on what I can do to stop "Lucy" (That's what my fiance calls me when I'm going nutty) from making my wedding a disaster? She's an emotional creature, that Lucy.
