Has anyone been diagnosed with PMDD? Or diagnosed themselves?

I am fairly certain this is what I have.

In the days-week leading up to AF, I get extremely emotional, teary, anxious, depressed, snappy.

Yesterday DF was saying how he would like to start collecting watches, and I got irrationally annoyed about it. I managed to somehow keep my annoyance to myself somewhat, but today I have totally lost it.
It started as a normal day, but its ended in me feeling like my family would be better off without me. I always end up feeling this way to some extent when I have my period. I am generally a happy, easy going person.

Last cycle DF bought me 2 packs of skittles, which was meant to last a while (obviously) but I ate the two packs in 2 days! Then last night, I'd had dinner (macaroni cheese, full of carbs!), which I then went on to eat nearly a whole packet of chips, a large freddo frog and 8 forreros, as well as a few other things that I munched on too. I would have also had the double brie with crackers and salami if I didnt control my urge. I have never noticed me bingeing before, not like this!

DF said today that he can not live with my moods, and to be honest, I dont blame him. I cant live with them either. I am so horrified by my performance today, I just want to die. The guilt is eating me up and I just wish so badly I could go back and have gone out today instead of subjecting him to my over emotional state.

The scary thing is that in my head I am telling myself "This isnt right, stop being like this, what ARE you doing?" but I am out of control. I can not control my actions until I have got it all out, until I have cried and screamed. I dont even know how to deal with my emotions, how can I expect DF to know how to?

I know its not right. I know I need to do something about it.

From things I have been reading, you can help PMDD with a special diet, and also becoming more active with excercise. Also the pill? I am on the pill, but I believe the YAS pill is the best for PMDD, I am on monofeme. I am not keen on going on antidepressants.

Please, please, please someone tell me they know what I am going through and tell me that there is a way to escape this, I cant live like this anymore and I can not put my family through it any more!
