Boo Hoo- woe is me!

I have just begun this process and don't think I can stand it. In the past three months I have gotten my periods very close one to the other. This month I had a period at the beginning of the month and am getting ready to have another one.
The worst part is, that for a least a week before the flow, I have aches and pains everywhere. My breasts feel like they have needles and darts constantly piercing me, while I am swollen from the waist down in every muscle and aperture with intense burning on both ends. The cramps run from my uterus down to my ankles and on my lower back. The pains keep me from a good night's sleep. I feel nausiated, exhausted and weak. This has gone on almost the entire month. I do use the progestin cream, but it doesn't seem to be doing anything, nor is consuming soy products.
Does anyone have any idea why such pronounced symptoms and what if anything can be done to alleviate them?
I hope someone has an answer, right now I can see why they talk about mood swings, I'd just like to cry out loud because of how I'm feeling.
